clocksource / ACPI: Add probing infrastructure for ACPI-based clocksources
DT enjoys a rather nice probing infrastructure for clocksources,
while ACPI is so far stuck into a very distant past.
This patch introduces a declarative API, allowing clocksources
to be self-contained and be called when parsing the GTDT table.
