[PATCH v2] power: supply: rk817: Fix unsigned comparison with less than zero

[Jiapeng Chong <jiapeng.chong@linux.alibaba.com>]

The tmp is defined as u32 type, which results in invalid processing of
tmp<0 in function rk817_read_or_set_full_charge_on_boot(). Therefore,
drop the comparison.

drivers/power/supply/rk817_charger.c:828 rk817_read_or_set_full_charge_on_boot() warn: unsigned 'tmp' is never less than zero.
drivers/power/supply/rk817_charger.c:788 rk817_read_or_set_full_charge_on_boot() warn: unsigned 'tmp' is never less than zero.
