[PATCH 1/9] metag: perf: fix core internal / perf channel mux

[James Hogan <james.hogan@imgtec.com>]

The value written to the PERF_ICOREx or PERF_CHANx register to select
the performance events for the core internal and perf channel events was
(tmp & 0x0f), but tmp was set to (config & 0xf0) so it would always be
0. Correct it to use config instead of tmp.
