ACPI: updates rtc-cmos device platform_data

Browse source

Update ACPI to export its RTC extension information through platform_data
to the PNPACPI or platform bus device node used on the system being set up.

This will need to be updated later to provide a firmware hook to handle
system suspend with an alarm pending.

Len notes that "Eventually we may bundle ACPI/PNP/PNPACPI..." but if/when
that happens, ACPI can simplify this without my help.

And until it does, the separate patch creating a platform_device (on all
X86_PC systems, even without ACPI) will be needed.
