Fix remaining sparse warnings in arch/arm/mach-omap2/. These fixes
mostly consist of:
- tagging appropriate integer<->pointer casts with __force
- marking private structures and functions as static; adding function
prototypes in .h files for public functions
- assigning NULL to pointers, not 0
- adding prototypes for *_init() functions in the appropriate header
files, and getting rid of the corresponding open-coded extern
prototypes in other C files
Also clean up checkpatch issues - this mostly involves converting some
asm/ includes to linux/ includes.
While here, shrink some bitfields in struct omap_pwm_led_platform_data
down to the smallest possible type.
