OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c

The OMAP1 clock code currently #includes a large .h file full of static
data structures.  Instead, define the data in a .c file.

Russell King <linux@arm.linux.org.uk> proposed this new arrangement:

    http://marc.info/?l=linux-omap&m=125967425908895&w=2

This patch also deals with most of the flagrant checkpatch violations.

While here, separate the mpu_rate data structures out into their own
files, opp.h and opp_data.c.  In the long run, these mpu_rate tables
should be replaced with OPP code.

Also includes a patch from Felipe Balbi <felipe.balbi@nokia.com> to
mark omap1_clk_functions as __initdata to avoid a section warning:
