Chris Wilson 69fdf4206a drm: Differentiate the lack of an interface from invalid parameter 
If the ioctl is not supported on a particular piece of HW/driver
combination, report ENOTSUP (aka EOPNOTSUPP) so that it can be easily
distinguished from both the lack of the ioctl and from a regular invalid
parameter.

v2: Across all the kms ioctls we had a mixture of reporting EINVAL,
ENODEV and a few ENOTSUPP (most where EINVAL) for a failed
drm_core_check_feature(). Update everybody to report ENOTSUPP.

v3: ENOTSUPP is an internal errno! It's value (524) does not correspond
to a POSIX errno, the one we want is ENOTSUP. However,
uapi/asm-generic/errno.h doesn't include ENOTSUP but man errno says

	"ENOTSUP and EOPNOTSUPP have the same value on Linux,
	but according to POSIX.1 these error values should be
	distinct."

so use EOPNOTSUPP as its equivalent.
