OMAP2 clock: convert clock24xx.h to clock2xxx_data.c, opp2xxx*

The OMAP2 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 prcm_config data structures out into their own
files, opp2xxx.h and opp24{2,3}0_data.c, and only build in the OPP tables
for the target device.  This should save some memory.  In the long run,
these prcm_config tables should be replaced with OPP code.

+ * The OMAP2 processor can be run at several discrete 'PRCM configurations'.
+ * These configurations are characterized by voltage and speed for clocks.
+ * The device is only validated for certain combinations. One way to express
+ * these combinations is via the 'ratio's' which the clocks operate with
+ * respect to each other. These ratio sets are for a given voltage/DPLL
+ * setting. All configurations can be described by a DPLL setting and a ratio
+ * There are 3 ratio sets for the 2430 and X ratio sets for 2420.
+ *
+ * 2430 differs from 2420 in that there are no more phase synchronizers used.
+ * They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
+ * 2430 (iva2.1, NOdsp, mdm)

+ * XXX Missing voltage data.
+ *
+ * THe format described in this file is deprecated.  Once a reasonable
+ * OPP API exists, the data in this file should be converted to use it.

+ * This is technically part of the OMAP2xxx clock code.
