spl: Allow enabling SPL_OF_REAL and SPL_OF_PLATDATA at the same time

Browse Source 
Sandbox unit tests in U-Boot proper load a test device tree to have some
devices to work with. In order to do the same in SPL, we must enable
SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When
generating platdata from a devicetree, it is expected that we will not need
devicetree access functions (even though SPL_OF_CONTROL is enabled). This
expectation does not hold for sandbox, so allow user control of
SPL_OF_REAL.

There are several places in the tree where conditions involving OF_PLATDATA
or OF_REAL no longer function correctly when both of these options can be
selected at the same time. Adjust these conditions accordingly.

Indicates that a real devicetree is available which can be accessed
at runtime. This means that dev_read_...() functions can be used to
read data from the devicetree for each device. This is true if
SPL_OF_CONTROL is enabled and not SPL_OF_PLATDATA
read data from the devicetree for each device. You do not need to
enable this option if you have enabled SPL_OF_PLATDATA.
