soc/amd/mendocino: Increase CBFS_MCACHE size 

CBFS_MCACHE is currently experiencing overflow with CBFS verification
enabled. Reduce the pre-x86 cbmem console size from ~5.5 KiB to 4 KiB.
This reduction along with the available free space in PSP shared buffer
(32 KiB) helps to increase the CBFS_MCACHE size from 8 KiB to required
14 KiB.

BUG=b:259342909
TEST=Build and boot to OS in Skyrim. Ensure that there are no CBFS
mcache overflows.
FMAP: area COREBOOT found @ 80a000 (8347648 bytes)
VB2:vb2_digest_init() 0 bytes, hash algo 2, HW acceleration unsupported
CBFS: mcache @0x00019a40 built for 67 files, used 0x19a0 of 0x1c00 bytes
CBFS: Found 'apu/amdfw_a' @0x0 size 0x3ff80 in mcache @0x0001b640
VB2:vb2_digest_init() 262016 bytes, hash algo 2, HW acceleration enabled
Ensure that firmware_CbfsMcache FAFT test is successful.
