misc: vexpress/spc: update get/set_perf to use frequency as input
This patch changes the input parameter of spc_get/spc_set_perf
routines to frequency instead of performance index as expected
by the firmware. The SPC driver now has the list of frequencies
supported by the firmware, so it can map the requested frequency
to the right performance index.
