[PATCH v4 1/3] gpio/mxs: Move Freescale mxs gpio driver to drivers/gpio

[Shawn Guo]

From: Grant Likely <grant.likely at secretlab.ca>

GPIO drivers are getting moved to drivers/gpio for cleanup and
consolidation.  This patch moves the mxs driver.  Follow up patches
will clean it up and make it a fine upstanding example of a gpio
driver.
