x86/idle: Use MONITOR and MWAIT mnemonics in <asm/mwait.h>
Current minimum required version of binutils is 2.25,
which supports MONITOR and MWAIT instruction mnemonics.
Replace the byte-wise specification of MONITOR and
MWAIT with these proper mnemonics.
No functional change intended.
Note: LLVM assembler is not able to assemble correct forms of MONITOR
and MWAIT instructions with explicit operands and reports:
error: invalid operand for instruction
monitor %rax,%ecx,%edx

Use instruction mnemonics with implicit operands to
work around this issue.
