pinctrl: bcm: fix kconfig dependency warning when !GPIOLIB
[ Upstream commit 513034d8b089b9a49dab57845aee70e830fe7334 ]
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.
