Juri Lelli	c105aa3118	arm,arm64,drivers: reduce scope of cap_parsing_failed ... Reduce the scope of cap_parsing_failed (making it static in drivers/base/arch_topology.c) by slightly changing {arm,arm64} DT parsing code. For arm checking for !cap_parsing_failed before calling normalize_ cpu_capacity() is superfluous, as returning an error from parse_ cpu_capacity() (above) means cap_from _dt is set to false. For arm64 we can simply check if raw_capacity points to something, which is not if capacity parsing has failed.

Juri Lelli	2ef7a2953c	arm, arm64: factorize common cpu capacity default code ... arm and arm64 share lot of code relative to parsing CPU capacity information from DT, using that information for appropriate scaling and exposing a sysfs interface for chaging such values at runtime. Factorize such code in a common place (driver/base/arch_topology.c) in preparation for further additions.
