Sherman Yin 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.

Heiko Stübner a7b3bf55e7 pinctrl: remove slew-rate parameter from tz1090
As the binding for slew-rate is under discussion and seems to need
more tought it will get removed for now, so it doesn't get an offical
release.

Therefore remove it again from the only current user, tz1090.

James Hogan b58f0273f0 pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver
Add a pin control driver for the TZ1090's low power pins via the
powerdown controller SOC_GPIO_CONTROL registers.

These pins have individually controlled pull-up, and group controlled
schmitt, slew-rate, drive-strength, and power-on-start (pos).

The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the
ir_mod_stable_out and ir_mod_power_out functions respectively. If no
function is set they remain in GPIO mode. These muxes can be overridden
by requesting them as GPIOs.
