gpio: dln2: fix issue when an IRQ is unmasked then enabled
As noticed during suspend/resume operations, the IRQ can be unmasked
then disabled in suspend and eventually enabled in resume, but without
being unmasked.
The current implementation does not take into account interactions
between mask/unmask and enable/disable interrupts, and thus in the
above scenarios the IRQs remain unactive.
To fix this we removed the enable/disable operations as they fallback
to mask/unmask anyway.
We also remove the pending bitmaks as it is already done in irq_data
(i.e. IRQS_PENDING).
