Handle the Unit field, which is needed to find the right PMU for
an event. We call it "pmu" and convert it to the perf pmu name
with an uncore prefix.
Handle the ExtSel field, which just extends the event mask with
an additional bit.
Handle the Filter field which adds parameter

The next patch needs to modify event code. Previously eventcode was just
passed through as a string. Now parse it as a number.

Many Motorola phones like droid 4 are using a custom PMIC called CPCAP
or 6556002. We can support it's core features quite easily with regmap_spi
