ARM: OMAP: Trivial driver changes to remove include plat/cpu.h
Drivers should not use cpu_is_omap or cpu_class_is_omap macros, they should be private to the platform init code. And we'll be removing plat/cpu.h and only have a private soc.h for the arch/arm/*omap* code. This patch is intended as preparation for the core omap changes and removes the need to include plat/cpu.h from several drivers. This is needed for the ARM common zImage support. These changes are OK to do because: - omap-rng.c does not need plat/cpu.h - omap-aes.c and omap-sham.c get the proper platform_data passed to them so they don't need extra checks in the driver - omap-dma.c and omap-pcm.c can test the arch locally as omap1 and omap2 cannot be compiled together because of conflicting compiler flags Cc: Deepak Saxena <dsaxena@plexity.net> Cc: Matt Mackall <mpm@selenic.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: David S.
