Dump pinmux register value, not only function part in the pinmux
register.
Also fix the issue on caluclating pin offset. The last parameter

Marvell's PXA/MMP silicon also match the behavior of pinctrl-single.
Each pin binds to one register. A lot of pins could be configured
as gpio.

v2:
1. Remove "pinctrl-single,gpio-mask". Since GPIO function is one of the
mux function in the pinmux register of both OMAP and PXA/MMP silicons.
Use "pinctrl-single,function-mask" instead.
2. Remove "pinctrl-single,gpio-enable" & "pinctrl-single,gpio-disable".

Mutex is locked duplicatly by pinconf_groups_show() and

Since pins are configured in device driver, pinctrl driver should be
loaded by those device driver. module_platform_driver() only declares
pinctrl driver is in module_initcall privilege. Use postcore_initcall
privilege instead.
