char: tpm: cr50: Remove IRQF_ONESHOT
Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also prevents force-threading of the primary handler and the
irq-core will warn about this.
Remove IRQF_ONESHOT from irqflags.
