As there is no threaded handler, replace devm_request_threaded_irq()
with devm_request_irq(), and as the handler calls iio_trigger_poll()
which may not be called from a threaded handler replace IRQF_ONESHOT
with IRQF_NO_THREAD.
Since commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT

xe_gsc_proxy_remove undoes what is done in both xe_gsc_proxy_init and
xe_gsc_proxy_start; however, if we fail between those 2 calls, it is
possible that the HW forcewake access hasn't been initialized yet and so
we hit errors when the cleanup code tries to write GSC register. To
avoid that, split the c... | ```diff

importantly, force delivery of the payload in *all* paths where userspace
