cpuidle, mwait: Make the mwait code noinstr clean
objtool found a few cases where this code called out into instrumented
code:
vmlinux.o: warning: objtool: intel_idle_s2idle+0x6e: call to __monitor.constprop.0() leaves .noinstr.text section
vmlinux.o: warning: objtool: intel_idle_irq+0x8c: call to __monitor.constprop.0() leaves .noinstr.text section
vmlinux.o: warning: objtool: intel_idle+0x73: call to __monitor.constprop.0() leaves .noinstr.text section
vmlinux.o: warning: objtool: mwait_idle+0x88: call to clflush() leaves .noinstr.text section
Fix it by marking the affected methods as __always_inline.
