bq27x00_battery: use unaligned access helper
has been removed from the -mm tree. Its filename was

Subject: bq27x00_battery: use unaligned access helper
From: Harvey Harrison <harvey.harrison@xxxxxxxxx>
Remove hand-rolled get_unaligned_be16, this points to a possible bug as
bq27x00_read does another endian byteswap which sparse notices:
drivers/power/bq27x00_battery.c:81:14: warning: cast to restricted __be16
Which should probably be checked.
