ARM: dts: msm: specify VDD_APC0/1 CPR floor voltage overrides on msm8994

Specify per-virtual-corner floor voltages for VDD_APC0 and
VDD_APC1 cpr-regulator devices which override the default
per-fuse-corner floor voltages.  The lower per-virtual-corner
values allow additional power to be saved on fast chips when
operating at the lower frequencies associated with a given fuse
corner.
