drivers: pinctrl: qcom: fix Kconfig dependency on GPIOLIB

When PINCTRL_MSM is enabled, and GPIOLIB is disabled,
Kbuild gives the following warning:

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

This is because PINCTRL_MSM selects GPIOLIB_IRQCHIP,
without selecting or depending on GPIOLIB, despite
GPIOLIB_IRQCHIP depending on GPIOLIB. Having PINCTRL_MSM
select GPIOLIB will cause a recursive dependency error.
