This groups USB PWEN and OVC pins together on R8A7791 SoC,
the same way it's done on R8A7790, since both are needed
for a USB device.

On non-DT platforms IRQ controllers associated with the GPIOs have a
fixed IRQ base value known at compile time. The sh-pfc driver translates
GPIO number to IRQ numbers using a hardcoded table. This mechanism
breaks on DT platforms, as the IRQ base values are dynamic in that case.
Fix this by specifying IRQs associated with GPIOs in IRQ resources,
populated automatically from the device tree. When IRQ resources are
specified the driver requires one IRQ resource per GPIO able to generate
an interrupt, and uses the translation table to compute the IRQ resource
offset instead of the IRQ number.

There are four I2C interfaces on r8a7790, each of them can be connected to
one of the two respective I2C controllers, e.g. interface #0 can be
configured to work with I2C0 or with IIC0. Additionally some of those
interfaces can also use one of several pin sets. Interface #3 is special,
because it can be used in automatic mode for DVFS. It only has one set
of pins available and those pins cannot be used for anything else, they
also lack the GPIO function.
This patch uses the sh-pfc ability to configure pins, not associated with
GPIOs and adds support for I2C3 to the r8a7790 PFC set up.

When setting pin configuration in the pinctrl framework, pin_config_set() or
pin_config_group_set() is called in a loop to set one configuration at a time
for the specified pin or group.
This patch 1) removes the loop and 2) changes the API to pass the whole pin
config array to the driver. It is now up to the driver to loop through the
configs. This allows the driver to potentially combine configs and reduce the
number of writes to pin config registers.
All c files changed have been build-tested to verify the change compiles and
that the corresponding .o is successfully generated.
