Expand CBFS_MCACHE from 16K to 22K to provide more space for
metadata caching. To accommodate this, shift FMAP_CACHE from
0x14860400 to 0x14861800.
Updated the memory map diagram in memlayout.ld to reflect the
new base address for the FMAP_CACHE region.
TEST=No CBFS related error seen while booting google/quartz.
w/o patch:
```
[ERROR] CBFS ERROR: mcache overflow, should increase CBFS_MCACHE size!
```
