Skip putting the GPIO module into a reset during the chip init. This makes
sure to preserve any existing GPIO configurations done by pre-kernel boot code.

On the TC35892, a random delayed interrupt clear (GPIO IC) write locks up the
child interrupts. In such a case, the original interrupt is active and not yet
acknowledged. Re-check the IRQST bit for any pending interrupts and handle
those.
