Subject: bq27x00_battery: Fix bugs introduced with BQ27425 support
From: NeilBrown <neilb@xxxxxxx>
commit bde83b9a6b44c1e0fd872e57ecc869cfcf88538f upstream.
commit a66f59ba2e994bf70274ef0513e24e0e7ae20c63
bq27x00_battery: Add support for BQ27425 chip
introduced 2 bugs.
1/ 'chip' was set to BQ27425 unconditionally - breaking support for
other devices;
2/ BQ27425 does not support cycle count, how the code still tries to
get the cycle count for BQ27425, and now does it twice for other chips.
