ACPI: PM: Add unused power resource quirk for THUNDEROBOT ZERO

Browse Source 
On the THUNDEROBOT ZERO laptop, the second NVMe slot and the discrete
NVIDIA GPU are both controlled by power-resource PXP. Due to the SSDT table
bug (lack of reference), PXP will be shut dow as an "unused" power resource
during initialization, making the NVMe slot #2 + NVIDIA both inaccessible.

This issue was introduced by commit a1224f34d7 ("ACPI: PM: Check
states of power resources during initialization"). Here are test
results on the three consecutive commits:

(bad again!) a1224f34d7 ACPI: PM: Check states of power resources during initialization
(good) bc28368596 ACPI: PM: Do not turn off power resources in unknown state
(bad) 519d81956e Linux 5.15-rc6

On commit bc28368596 ("ACPI: PM: Do not turn off power resources in
unknown state") this was not an issue because the power resource state
left UNKNOWN thus being ignored.

See also commit 9b04d99788 ("ACPI: PM: Do not turn of unused power
resources on the Toshiba Click Mini") which is another almost identical
case to this one.
