ARM: pinctrl: Add Broadcom Capri pinctrl driver

Browse Source 
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.

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