ARM: dts: msm: disable VDD_GFX CPR aging adjustments on MSM8998v2

Disable VDD_GFX CPR aging measurement and adjustments for all
global CPR fusing revisions.  The initial aging sensor difference
fuse will not be blown on parts with revision 3 so software must
not attempt to perform an aging measurement on these parts.  It
is unknown which future revision will end up utilizing aging so
also disable aging measurements on all future revisions as well.

Modify the open-loop and closed-loop voltage adjustments
accordingly so that the maximum 15 mV aging margin is present
for all CPR revisions.
