pinctrl: samsung: Remove bogus irq_[un]mask from resource management
commit 3fa53ec2ed885b0aec3f0472e3b4a8a6f1cd748c upstream.
The irq chip callbacks irq_request/release_resources() have absolutely no
business with masking and unmasking the irq.
The core code unmasks the interrupt after complete setup and masks it
before invoking irq_release_resources().
The unmask is actually harmful as it happens before the interrupt is
completely initialized in __setup_irq().
Remove it.
