Patrick Delaunay d72e7bbe7c ram: stm32mp1: compute DDR size from DDRCTL registers 
Compute the DDR size from DDR controller register (mstr and addrmap)
in U-Boot proper as the DDR information are useful only for SPL
but not for U-Boot proper, for example with TFABOOT.

This patch simplify U-Boot DT when several DDR size are supported
and support of next SOC in STM32MP family.
