There's no need to use '__builtin_choose_expr' to choose the right
call to 'adis_update_bits_base()'. We can change the 'BUILD_BUG_ON()'
condition so that it makes sure only the supported sizes are
passed in. With that, we can just use 'sizeof(val)' as the size argument
of 'adis_update_bits_base()'.
