charger: bd99955: Remove incorrect VSYSVAL_THL / THH settings

Browse Source 
VSYSVAL_THL / THH are high / low hysteresis values below which dead
battery condition is triggered, which doesn't match our register
configuration. Leave these regs at default for now until we better
understand the effect of dead battery detection.

BUG=chrome-os-partner:55626
BRANCH=None
TEST=Manual on kevin with other pending changes, verify dead battery
successfully charges.
