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.

114 Say Y here to support Broadcom Capri pinctrl driver, which is used for
115 the BCM281xx SoC family, including BCM11130, BCM11140, BCM11351,
116 BCM28145, and BCM28155 SoCs. This driver requires the pinctrl
117 framework. GPIO is provided by a separate GPIO driver.
