[PATCH V2 1/6] pinctrl: pinctrl-single: use arch_initcall and module_exit

[Vishwanathrao Badarkhe, Manish]

Currently, I2C driver gets probed before pinctrl driver.
To achieve I2C pin muxing via pinctrl driver before I2C
probe get called, register pinctrl driver in arch_initcall.
Also, add module_exit to unregister pinctrl driver.
