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.
