ACPI: Add CMOS RTC Operation Region handler support
On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and the EC's _REG methord accesses that region. Thus an appropriate address space handler must be registered for that region before the EC driver is loaded. Introduce a mechanism for adding CMOS RTC address space handlers. Register an ACPI scan handler for CMOS RTC devices such that, when a device of that kind is detected during an ACPI namespace scan, a common CMOS RTC operation region address space handler will be installed for it.
