drivers: Replace DEV_INVALID_OP by -ENOTSUP

This patch replaces all occurences of the macro DEV_INVALID_OP by
-ENOTSUP at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.
