mb/google/bluey: Update flash layout

Browse source 
This patch updates flash layout for Bluey as below:

WP_RO:  4MB -> 12MB
 |
 |----> bootblock: 120KB -> 512KB
 |
 |----> FMAP: Start offset 0x3c0000 -> Start offset post bootblock
 |
 |----> CBFS: Start offset post bootblock -> Start offset post FMAP
 |
 |----> RO_VPD: Limit size to 16KB

RW_MISC: 128KB -> 120KB

RW_SECTION_A/B: 1536KB -> 1984KB

This patch allows COREBOOT CBFS to grow beyond 3.75MB as per
planned growth in CBFS (inside WP_RO) due to the addition of SoC
firmware binaries.

TEST=Able to build AP FW image for google/bluey.
