pinctrl: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

pinctrl: sunxi: sun50i-h5: Switch to use dev_err_probe() helper

In the probe path, dev_err() can be replace with dev_err_probe()
which will check if error code is -EPROBE_DEFER and and prints the
error name.

pinctrl: sunxi: sun50i-h5 use platform_irq_count

platform_irq_count() is the more generic way (independent of
device trees) to determine the count of available interrupts. So
use this instead.

As platform_irq_count() might return an error code (which
of_irq_count doesn't) some additional handling is necessary.

pinctrl: sunxi: Disable strict mode for H5 driver

All of the H5 boards in the kernel reference the MMC0 CD pin twice in
their DT, so strict mode will make the MMC driver fail to load.
To keep existing DTs working, disable strict mode in the H5 driver.

pinctrl: sunxi: fix wrong irq_banks number for H5 pinctrl

The pin controller of Allwinner H5 has three IRQ banks, however in old
versions of drivers and device trees, only two are set, which makes
PG bank IRQ not available.

If it's directly set to 3, the old device trees will fail to boot.

Add a workaround (and a warning) for older device trees, and allow new
device trees to use correct 3 IRQ banks.

drivers: pinctrl: add driver for Allwinner H5 SoC

Based on the Allwinner H5 datasheet and the pinctrl driver of the
backward-compatible H3 this introduces the pin multiplex assignments for
the H5 SoC.

H5 introduced some more pin functions (e.g. three more groups of TS
pins, and one more groups of SIM pins) than H3.
