ARM: dts: msm: update VDD_APC0/1 CPR loop configurations for sdm845

Reduce the consecutive down setting from 2 to 0 for all threads
on both VDD_APC0 and VDD_APC1 CPRh controllers.  This ensures
the that the CPRh controllers settle the supply voltage down to
the closed-loop voltage very quickly after each OSM triggered
corner switch.

Also increase the count repeat setting for both controllers from
1 to 20 in order to avoid oscillating up, down, up, down voltage
stepping due to PFM voltage ripple.
