[PATCH v2 1/2] remoteproc: qcom_q6v5_pas: disable wakeup on probe fail or remove

[Luca Weiss]

Leaving wakeup enabled during probe fail (-EPROBE_DEFER) or remove makes
the subsequent probe fail.

[    3.749454] remoteproc remoteproc0: releasing 3000000.remoteproc
[    3.752949] qcom_q6v5_pas: probe of 3000000.remoteproc failed with error -17
[    3.878935] remoteproc remoteproc0: releasing 4080000.remoteproc
[    3.887602] qcom_q6v5_pas: probe of 4080000.remoteproc failed with error -17
[    4.319552] remoteproc remoteproc0: releasing 8300000.remoteproc
[    4.332716] qcom_q6v5_pas: probe of 8300000.remoteproc failed with error -17

Fix this by disabling wakeup in both cases so the driver can properly
probe on the next try.

Fixes: dc86c129b4fb ("remoteproc: qcom: pas: Mark devices as wakeup capable")
