by using helper functions clk_prepare_enable/clk_disable_unprepare.

The merge commit "526b2641 Merge branch 'imx/cleanup' into imx/devel"
left a duplicated mx28_add_mxs_mmc() call, which causes the problem
below during boot.

  kobject_add_internal failed for mxs-mmc.1 with -EEXIST, don't try
  to register things with the same name in the same directory.

The patch removes this leftover and also change mmc0 adding to align
with mmc1.

Currently framebuffer and MMC devices are registered even if their associated
GPIO pins fail to be requested.

Change the logic so that the registration of such devices only occurs if their
GPIO requests succeeded.

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.

v2: Removed header file entirely and put struct definition directly
    into driver.  The struct isn't used anywhere else in the kernel.

Current code does not set the GPIO value to zero as mentioned in the comment.

Fix it by setting the initial GPIO value to zero.
