[PATCH v4 12/13] soundwire: amd: fix IRQ thread dropping STATUS_0TO7 on simultaneous wake

[Vijendar Mukunda <Vijendar.Mukunda@amd.com>]

When a wake interrupt and a device-state change arrive simultaneously,
the IRQ thread used an early return after detecting the wake bit,
silently discarding STATUS_0TO7.

When the manager is already at D0, pm_request_resume() is a no-op and
amd_resume_runtime() is never called, so the dropped ATTACHED event
cannot be recovered and jack detection stops working.

Remove the early return: call amd_sdw_process_wake_event() inside a
conditional block and fall through to the normal slave-status processing
path. Mask AMD_SDW_WAKE_STAT_MASK out of the local status_change_8to11
copy after handling the wake event so the remaining interrupt bits are
processed without re-entering the wake path.

Fixes: 66c878838f37 ("soundwire: amd: handle SoundWire wake enable interrupt")
