[PATCH] cleanup asm/setup.h userspace visibility

Make the contents of the userspace asm/setup.h header consistent on all
architectures:

 - export setup.h to userspace on all architectures
 - export only COMMAND_LINE_SIZE to userspace
 - frv: move COMMAND_LINE_SIZE from param.h
 - i386: remove duplicate COMMAND_LINE_SIZE from param.h
 - arm:
   - export ATAGs to userspace
   - change u8/u16/u32 to __u8/__u16/__u32
