arm64: renesas: Introduce renesas_dram_init_banksize()

Introduce weak renesas_dram_init_banksize() function which is meant
to be used to adjust DRAM bank sizes after the common Renesas board
DRAM bank handling code finished. This is mainly meant for boards
which ship with multiple DRAM size options, which can be detected
at runtime. This allows such boards to ship with single U-Boot
binary on all boards.
