[PATCH] imx8m: fix cache setup for dynamic sdram size

[sbabic at denx.de]

> the mem_map structure containing the size of SDRAM is used in various
> cache functions in cache_v8.c thus we need to update it with the
> sdram size the board is configured with as well. Without this
> the cache functions do not get setup properly and can hang
> in the case where a board reports more SDRAM than defined in
> PHYS_SDRAM_SIZE.
