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.
