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.

Move CHIPSET_METEOR_LAKE to the bottom of the ich_chipset list to ensure
that all the newer chipsets in the future will use BIOS_BM check by
default.

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
