power: supply: axp288_charger: Round constant_charge_voltage writes down

Browse source 
commit 81af7f2342d162e24ac820c10e68684d9f927663 upstream.

Round constant_charge_voltage writes down to the first supported lower
value, rather then rounding them up to the first supported higher value.

This fixes e.g. writing 4250000 resulting in a value of 4350000 which
might be dangerous, instead writing 4250000 will now result in a safe
4200000 value.
