Add support for reset -c flag to explicitly request cold reset.
This provides symmetry with -w (warm) and -u (firmware UI) flags.
For EFI apps, this performs EFI_RESET_COLD which does a full system
reboot without going to firmware setup interface.

efi: Improve integration of the app with a Shim environment
This series collects together various small fixes and improvements which
make it easier to use the U-Boot EFI app in a bootflow which includes
Shim:
- 'Reset' back to the caller (e.g. EDK2)
- Machine reset using cold and warm reset
- Reset and enter the firmware UI
- Shim command now supports persistent debug
- Bootmenu shows the real media for each bootflow rather than just 'efi'
