pinctrl: qcom: make the pinmuxing strict
The strict flag in struct pinmux_ops disallows the usage of the same pin
as a GPIO and for another function. Without it, a rouge user-space
process with enough privileges (or even a buggy driver) can request a
used pin as GPIO and drive it, potentially confusing devices or even
crashing the system. Set it globally for all pinctrl-msm users.
