Add a keyboard driver which returns keys produced by EFI.
This is basically the same as the serial driver but it doesn't combine
input and output into one driver, allowing more control when using a
separate screen.
Add the required devicetree fragment for ARM (only).

Cover-letter:
efi: Tidy up some commands and provide a keyboard driver
This series collect various odds and ends to make the ARM EFI app show
a menu that looks reasonable, including truetype fonts and a new
keyboard driver, selectable by setting stdin to 'efi-kbd'.
Some highlights:
- fix some bugs in addr_find and part_find and adds docs / tests
- reset pager when clearing the console
- use at least 1G of memory with EFI since the app allocates 512M
- allow NEON registers so floating point can work (truetype)
- show the global_data flags with bdinfo

In some cases the device may have a touchpad or mouse, so it is useful
to be able to use this in U-Boot. Add a simple driver for a mouse that
uses the EFI simple-pointer protocol.

Add a basic mouse driver for USB mice. It only handles very basic mice so
assumes that the reports are in the basic format described by the USB HID
specification 1.11.

When running a simple GUI it is useful to support a mouse. This is
similar to what is provided in UEFI's boot menu. Add a simple uclass and
a way to read the mouse position.
For sandbox add a driver that reads the position from SDL. Disable input
for the tools-only build, since it is of no use there and causes build
failures.

Bootmenu requires an input device with arrows and enter key.
A common smartphone luckily has power, volume up/down buttons,
which may be used for controlling bootmenu.
To use driver, add 'button-kbd' to stdin.

This driver adds support for the keyboard on Apple Silicon laptops.
The controller for this keyboard sits on an SPI bus and uses an
Apple-specific HID over SPI protocol. The packets sent by this
controller for key presses and key releases are fairly simple and
are decoded directly by the code in this driver and converted into
standard Linux keycodes. The same controller handles the touchpad
found on these laptops. Packets for touchpad events are simply
ignored.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

Add a module which understands converting key codes (or scan codes)
to ASCII characters. It includes FIFO support and can call back to
drivers to read new characters when its FIFO is empty.
Keycode maps are provided for un-modified, shift and ctrl keys.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
