523bc3820f mfd/tc3589x: undo gpio module reset during chip init
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.

bd77efd0ce mfd/tc3589x: fix random interrupt misses
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.
