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.

The mxs duart is actually an amba-pl011 device. This commit changes
the duart device code to dynamically allocate amba-pl011 device,
so that drivers/serial/amba-pl011.c can be used on mxs.
