Currently 2.5 GB is calculated as DRAM size for a 1 GB RK322x board
if CONFIG_SPL_OPTEE is set. This is troublesome when booting a
linux kernel since this size will be injected in FDT of the kernel.
gd->bd->bi_dram[0].start (which is basically CONFIG_SYS_SDRAM_BASE)
must not be taken into consideration for calculation of second bank
size, since this offset is already included in calculation of "top".
After applying this patch 992 MB (1024 MB - 32 MB reserved for
optee-os) is correctly calculated and has also been verified on
2 GB boards.
