pinctrl: qcom: restrict drivers per ARM/ARM64

There is no point to allow selecting pin-controller drivers for Qualcomm
ARMv7 SoCs when building ARM64 kernel, and vice versa.  This makes
kernel configuration more difficult as many do not remember the Qualcomm
SoCs.  There won't be a single image for ARMv7 and ARMv8/9 SoCs, so no
features/options are lost.
