Rename raw_read8 to st_raw_read8 and statically inline in the header
file. Removing the extern removes linker warnings when including this
header file without the driver, which happens in baseboard files.
BRANCH=none
BUG=none
TEST=including "driver/accelgyro_lsm6dsm.h" in c files that
do not link the actual driver will now compile.
