f6aaaac999 sh-pfc: r8a7790: add pin definitions for the I2C3 interface
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.

03b054e969 pinctrl: Pass all configs to driver on pin_config_set()
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.
