[PATCH] ARM: Exynos4: Turn off clocks for NAND, OneNAND and TSI controllers

The clocks for NAND, OneNAND and Transport Stream Interface(TSI)
controllers could be either enabled or disabled at boot. To ensure
that these are turned off until used, add them to the list of clocks
to be turned off during boot.
