ichspi.c: Add support for region 9 and beyond in Meteor Lake
Since Meteor Lake, configuring region access for FREG9 and higher is
necessary. This configuration is determined using BIOS_BM registers:
BIOS_BM_RAP (Offset 0x118): BIOS Master Read Access Permissions.
Each bit [15:0] corresponds to a region [15:0].
A set bit grants BIOS master read access.
BIOS_BM_WAP (Offset 0x11c): BIOS Master Write Access Permissions.
Each bit [15:0] corresponds to a region [15:0].
A set bit grants BIOS master write/erase access.
BUG=b:319773700, b:304439294
BUG=b:319336080
TEST=On MTL, use flashrom -VV to see correct FREG9 access
TEST=On ADL, use flashrom -VV to see not break anything
