ARM: dts: msm: update APCC CPR floor voltages for msm8996



Device characterization has shown that it is safe to use lower
per-corner CPR floor voltages in place of per-fuse-corner
floor voltages for both APCC thread 0 (power cluster + CBF) and
thread 1 (performance cluster).  The new lower floor values will
result in power savings on chips that were limited by the
previous floor voltages.

Ensure that the floor voltages specified for the APCC thread 0
corners are high enough for the corresponding frequencies of
both the power cluster clock and the CBF clock.
