930bf02299 mfd: Guard tc3589x PM methods with CONFIG_PM_SLEEP
Guard PM methods with CONFIG_PM_SLEEP and get rid of some unneeded #ifdefs.
This fixes below build warnings:

  CC      drivers/mfd/tc3589x.o
drivers/mfd/tc3589x.c:361:12: warning: 'tc3589x_suspend' defined but not used [-Wunused-function]
drivers/mfd/tc3589x.c:375:12: warning: 'tc3589x_resume' defined but not used [-Wunused-function]

SIMPLE_DEV_PM_OPS already defines constant dev_pm_ops, thus also fix
'duplicate const' sparse warning.

54d8e2c323 mfd: Add missing #ifdef around tc3589x PM block
The CONFIG_PM code was unconditionally compiled in despite
the dev_pm_ops only being included into the driver struct
if used. Fix this by adding the missing #ifdef.

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.
