[PATCH v6 0/4] Bluetooth: btintel_pcie: fix D-state transitions and PM flows

[Ravindra <ravindra@intel.com>]

This series fixes the suspend/resume path of btintel_pcie.

Patch 1 refreshes the boot-stage register before the fallback state check.
Patch 2 distinguishes S0ix from S3/S4 and routes thaw through a normal D0
transition. Patch 3 verifies the state after GP0 and completes any missing
RX or mailbox setup. It also serializes the alive-context claim between the
GP0 handler and the PM fallback so only one path reinitializes the RX ring.
Patch 4 clears the GP0 cause with a direct W1C write.
