[PATCH 6/6] platform-x86: msi-wmi-platform: Add Gen 4 device

["Derek J. Clark" <derekjohn.clark@gmail.com>]

Adds support for the MSI Claw 8 EX AI+. This device uses a unique new
shift mode for custom TDP not previously exposed by this driver. To
ensure that "MSI_SHIFT_MODE_USER" can still be set in the future to
CUSTOM platform profile, store the shift mode that applies to custom in
the quirks and check it outside the switch case in _get() since it is no
longer a compile time const.
