ACPI: x86: cmos_rtc: Create a CMOS RTC platform device
Make the CMOS RTC ACPI scan handler create a platform device that will
be used subsequently by rtc-cmos for driver binding on x86 systems with
ACPI and update add_rtc_cmos() to skip registering a fallback platform
device for the CMOS RTC when the above one has been registered.
