Subject: [RFC PATCH v2 04/12] openrisc: Don't pull in all of linux/bitops.h in asm/cmpxchg.h

The openrisc implementation of asm/cmpxchg.h pulls in linux/bitops.h
so that it can refer to BITS_PER_BYTE. It also transitively relies on
this pulling in linux/compiler.h for READ_ONCE.

Replace the #include with asm-generic/bits.h and linux/compiler.h
