Subject: [ 52/56] mmc: sdhci-s3c: fix the wrong number of max bus clocks

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jaehoon Chung <jh80.chung@...sung.com>

commit 5feb54a1ab91a237e247c013b8c4fb100ea347b1 upstream.

We can use up to four bus-clocks; but on module remove, we didn't
disable the fourth bus clock.
