pinctrl: qcom: add PINCTRL_QCOM_GENERIC to enable all drivers by default

Introduce a new Kconfig option PINCTRL_QCOM_GENERIC that, when selected,
enables all Qualcomm pinctrl drivers by default. This simplifies defconfigs
for platforms supporting multiple SoCs and avoids manual driver selection.
Individual drivers can still be disabled if required.
