ARM: msm: dts: Add support for 1.7GHz for MSM8939

Add a new speed bin to identify 1.7GHz. Add additional
cpu frequencies supported. Add the corresponding CCI,
BW and virtual corner mappings.

The Max corner values for each of the client(Perf/power/CCI)
has changed, thus in most of the cases the regulator framework
is unable to find a common max voltage corner to apply and
ends up honoring only the first client. Add dummy Fmax for
Power cluster and CCI to map with max corner of perf cluster
to satisfy the same.
