soc/mediatek/mt8186: Enlarge CBFS_MCACHE to 16K 

The per-file hash for CBFS_VERIFICATION, stored as a CBFS file
attribute, would increase the total RO metadata size by 75% (3796->6656
for corsola). Therefore, in order to make RO metadata cache fit into
CBFS_MCACHE, enlarge it from 8K to 16K.

Adjust the memlayout by decreasing the DRAM_INIT_CODE from 196K to 184K
(only 160K needed for now), and moving VBOOT2_WORK region to L2C. Also
shuffle the regions in SRAM with better comments.

TEST=emerge-corsola coreboot
TEST=Enabled CBFS_VERIFICATION and booted kingler into kernel
BRANCH=none
