pinctrl: uniphier: support pin configuration
Support the following DT properties:
"bias-disable"
"bias-pull-up"
"bias-pull-down"
"bias-pull-pin-default"
"input-enable"
"input-disable"
My main motivation is to support pull up/down biasing. For Pro5 and
later SoCs, the pupdctrl register number is the same as the pinmux
number, so this feature can be supported without having big pin
tables.
