Subject[065/244] mmc: rename mmc_host_clk_{ungate|gate} to mmc_host_clk_{hold|release}
3.0-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Mika Westerberg <mika.westerberg@linux.intel.com>

commit 08c14071fda4e69abb9d5b1566651cd092b158d3 upstream.

As per suggestion by Linus Walleij:

> If you think the names of the functions are confusing then
> you may rename them, say like this:
>
> mmc_host_clk_ungate() -> mmc_host_clk_hold()
> mmc_host_clk_gate() -> mmc_host_clk_release()
>
> Which would make the usecases more clear
(This is CC'd to stable@ because the next two patches, which fix
observable races, depend on it.)
