With the legacy clock support gone, this is no longer needed under
platform code-base. Thus, move this under the TI clock driver, and
remove the exported API from the public header.

With the legacy clock support gone, the OMAP interface clock implementation
can be moved under the clock driver. Some temporary header file tweaks are
also needed to make this change work properly.

Instead, copy the used constants from the header file to the source file.
This allows the code to be migrated under drivers folder where we don't
have access to the OMAP specific header files.

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.

Convert all OMAP3 specific platform files to use COMMON clk
and keep all the changes under the CONFIG_COMMON_CLK macro check
so it does not break any existing code. At a later point switch
to COMMON clk and get rid of all old/legacy code.

Convert all OMAP4 specific platform files to use COMMON clk
and keep all the changes under the CONFIG_COMMON_CLK macro check
so it does not break any existing code. At a later point switch
to COMMON clk and get rid of all old/legacy code.

This converts all apis which will be called directly from COMMON
clk to take a struct clk_hw parameter, and all the internal platform
apis to take a struct clk_hw_omap parameter.

Changes are based off the original patch from Mike Turquette.
