ARM: stm32mp: add helper for querying ram size
The STM32MP DDR Controller has a very flexible way of mapping address
bits to columns/rows/banks. This is so far configured by the ARM TF-A
as part of the SDRAM setup, so we don't need to do this in barebox.
Nevertheless reading it out in barebox, allows us to determine unused
address bits and thus the total size of SDRAM configured.
Add a barebox_arm_entry wrapper that computes the SDRAM size internally,
so boards may drop their hard-coded RAM size specifications.
