pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a selected config

This patch reworks PINCTRL_MSM to be a visible option, and
instead of having the various SoC specific drivers select
PINCTRL_MSM, this switches those configs to depend on
PINCTRL_MSM.

This is useful, as it will be needed in order to cleanly support
having the qcom-scm driver, which pinctrl-msm calls into,
configured as a module. Without this change, we would eventually
have to add dependency lines to every config that selects
PINCTRL_MSM, and that would becomes a maintenance headache.

We also add PINCTRL_MSM to the arm64 defconfig to avoid
surprises as otherwise PINCTRL_MSM/IPQ* options previously
enabled, will be off.
