ACPI: processor: Provide empty stub of acpi_proc_quirk_mwait_check()

Browse source 
Commit 0a0e2ea642 ("ACPI: processor: Move MWAIT quirk out of
acpi_processor.c") added acpi_proc_quirk_mwait_check() that is
only defined for x86 and is unlikely to be defined for any other
architectures, so put it under #ifdef CONFIG_X86 and provide
an empty stub implementation of it for the other cases.

This is kind of orthogonal to [1], because if any architectures other
than x86 decide to use the processor _OSC, they will see the reported
build error.
