power: pm8921-charger: adjust vdd max earlier
The charger hardware decides Constant Current VS Constant Voltage based
on the VPH_PWR voltage and not on battery voltage (vbatt) as it should.
The problem is, becuase of IR drop between VPH_PWR and VBATT, VPH_PWR
reaches the voltage programmed in vdd_max earlier while the VBATT stays
lower causing the charger hardware switch to constant voltage mode
prematurely.
To fix this issue adjust the vdd_max early.
