arm,arm64,drivers: move externs in a new header file Create a new header file (include/linux/arch_topology.h) and put there declarations of interfaces used by arm, arm64 and drivers code.

arch_topology: Change return type of topology_parse_cpu_capacity() to bool topology_parse_cpu_capacity() returns 1 on success and 0 on errors. Make it return bool instead of int as that suits the purpose better.

arm,arm64,drivers: add a prefix to drivers arch_topology interfaces Now that some functions that deal with arch topology information live under drivers, there is a clash of naming that might create confusion. Tidy things up by creating a topology namespace for interfaces used by arch code; achieve this by prepending a 'topology_' prefix to driver interfaces.
