ACPI: battery: Fix bogus cycle count values on systems without _BIX
Devices supporting only the legacy _BIF ACPI control method cannot
know the cycle count of the associated battery, so cycle_count always
remains 0. Claiming support for POWER_SUPPLY_PROP_CYCLE_COUNT on
such devices can thus mislead userspace applications and prevents
power supply extensions from supplying correct cycle count values.
Fix this by not claiming support for POWER_SUPPLY_PROP_CYCLE_COUNT
on devices without _BIX.
