gpio/mxs: Change gpio-mxs into an upstanding gpio driver

Browse source 
The patch makes necessary changes on gpio-mxs as below to turn it
into an upstanding gpio driver.

 * Clean up the gpio port definition stuff

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxs_gpio_init into mxs_gpio_probe function

And it then migrates mach-mxs to the updated driver by adding
corresponding platform devices.
