bq27x00_battery: Fix flag register read
When reading flags, bq27x00_read() argument is inverted and causes reads 2 of bytes for bq27200 and 1 byte for bq27500, while their register sizes are 1 and 2 bytes respectively. This causes bq27500 upper flag bits always to be returned as 0, causing full charge state to never be reported correctly, so fix it.
