ARM: pinctrl: Add Broadcom Capri pinctrl driver
Adds pinctrl driver for Broadcom Capri (BCM281xx) SoCs.
v4: - PINCTRL selected in Kconfig, PINCTRL_CAPRI selected in bcm_defconfig
- make use of regmap
- change CAPRI_PIN_UPDATE from macro to inline function.
- Handle pull-up strength arg in Ohm instead of enum
v3: Re-work driver to be based on generic pin config. Moved config selection
from Kconfig to bcm_defconfig.
v2: Use hyphens instead of underscore in DT property names.
