If the PWM pinctrl uses default state, the iomux setting will
be done at probe, the PWM may not be enabled at this moment.
It will make PWM into an intermediate state, destroy the default
hardware state, the PWM is not ready for work yet. So it is better
for doing PWM pinctrl setting after PWM enabled.

If some PWM enable_conf was configured with different values at
uboot/loader, the enable_conf should be cleaned firstly and
configured them at kernel. It is better to use the same parameters
on both sides to ensure excessive smoothing.

Since opp-suspend of cpub/l is 216MHz@950000mV, and the max frequency
under 950000mV is 600MHz, so initialize cpub/l freq to 600MHz.

Native sdmmc does not use rpm, but we set pm_runtime_force_suspend()
and pm_runtime_force_resume() for sleep PM. pm_runtime_force_*()
will check rpm status, so that the it doesn't call the resume
callback if we didn't increase its usage count.
Another drive-by fix is to de-init rpm once when rpm is used.

This's what mmc_select_hs400() or mmc_select_hs() did,
since mmc_set_clock() will let sdhci_arasan_set_clock()
update the PHY clock to match the timing, otherwise
the following mmc_switch_status() will be failed.

If the gpio IRQ type changes, it is possible to accidentally trigger
an interrupt, such as when the input is high, changed from level to
rise edge. For now, the best way to do this is to disable the INTEN
bit first, then configure the type to stagger this period of time.

The interrupt is requested before the device is powered on and
it's value in some cases cannot be reliable. It happens on some
devices that an interrupt is generated as soon as requested
before having the chance to disable the irq.
