mb/google/nissa: Modify FMD to redistribute buffer

Modify the chromeos FMD file for nissa variants to redistribute the
buffer in SI_ME region obtained due to CSE size optimizations to SI_BIOS
region.

1. Modify SI_ALL region size to 3712K. SI_DESC remains at 4K and SI_ME
is 3708K.
2. Modify SI_BIOS region to 12672K. This results in an addition of 32K
buffer each to FW_MAIN_A/B regions.
