Several pieces of stm32mp1 code call get_embedded_dt(), then use the
resulting pointer without checks, or initiate a panic if it is NULL.
Thus hitting this code results in a non-working binary. For example:
"PLATFORM=stm32mp1 CFG_DT=y"
The get_embedded_dt() uses were #ifdef'd out based on CFG_DT. However,
as shown, this is problematic, as the calls assumed a valid fdt must
be returned. A non-NULL fdt can be guaranteed with CFG_EMBED_DT, so
use this as the basis for the #ifdefs.
