ARM: OMAP2+: clock: use driver API instead of direct memory read/write

Browse Source 
Clock nodes shall use the services provided by underlying drivers to access
the hardware registers instead of direct memory read/write. Thus, change
all the code to use the new omap2_clk_readl / omap2_clk_writel APIs for this.
