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