power: supply: bq27xxx: fix reporting critical level

The EDV1/SOC1 flag is set when the battery voltage drops below the
threshold set in EEPROM. From observing the capacity_level reported by
the driver, and reading the datasheet, EDV1 remains set even when
EDVF/SOCF gets set. Thus, bq27xxx_battery_capacity_level() never reaches
the CAPACITY_LEVEL_CRITICAL code path, since CAPACITY_LEVEL_LOW takes
precedence.

This commit fixes the issue by swapping the order in which the flags are
tested. It was tested with bq27200 in the Nokia N900.
