locking/atomics/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 <linux/bits.h> and <linux/compiler.h>.
