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.
