power_supply: bq27x00: remove double endian swap
The bq27x00 registers are little endian, so just read them as such and don't do double endian swap on LE machines. This also gets rid of strange looking shift that was done after reading 8bit register because endian swap in bq27x00_read() was messing it up.
