soc/mediatek/mt8186: Adjust usage of SRAM L2C

We use parts of SRAM_L2C as the memory of PRERAM_CBMEM_CONSOLE before
DRAM calibration. When we check cbmem, we found the content of this
memory is unreadable.

The L3 (can be used as SRAM_L2C) is 1MB in total. However the BootROM
has configured only half of L2/L3 cache as SRAM. Therefore, decrease
the size of each SRAM region to fit into the first half of the cache.

BUG=b:207725851
TEST=Bootblock log looked good in `cbmem -c`
