pinctrl: qcom: sdx55: update kconfig dependency

Commit be117ca32261 ("pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a
dependency rather then a selected config") moved the qcom pinctrl drivers
to have PINCTRL_MSM as dependency rather then a selected config, so do
this change for SDX55 pinctrl driver as well.
