Subject: [PATCH] pinctrl: bcm: fix kconfig dependency warning when !GPIOLIB

When PINCTRL_BCM2835 is enabled and GPIOLIB is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for GPIOLIB_IRQCHIP
Depends on [n]: GPIOLIB [=n]
Selected by [y]:
- PINCTRL_BCM2835 [=y] && PINCTRL [=y] && OF [=y] && (ARCH_BCM2835 [=n] || ARCH_BRCMSTB [=n] || COMPILE_TEST [=y])

The reason is that PINCTRL_BCM2835 selects GPIOLIB_IRQCHIP without
depending on or selecting GPIOLIB while GPIOLIB_IRQCHIP is subordinate to
GPIOLIB.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.
