[PATCH 6/7][RFC] OMAP4: Clock hack since clock management framework not in.

[Santosh Shilimkar <santosh.shilimkar@ti.com>]

This patch update the cooomon clock.c file for OMAP4. The clk_get() and
clk_put() sunctions are moved to  common place in arch/arm/common/clkdev.c
Since on current OMAP$ platform clk management is still not supported, the
internal file is hacked.
Once the framework is ready the CONFIG_CLKDEV will be used.
