mb/google/volteer: Update flashmap descriptor for CSE Lite FW update 

To support CSE Lite firmware update, CSE RW partition is extracted from
CSE blob binary and added to FW_MAIN_A and FW_MAIN_B.

CSE RW size for TGL is close to 2.3MB; hence, the size of FW_MAIN_A and
FW_MAIN_B is increased to avoid an overflow.

BUG=b:140448618
TEST=build with me_rw binary blob for volteer and boot to kernel.
