add graphics/drm-devel-kmod

Add graphics/drm-devel-kmod, development version of the lkpi based DRM
graphics drivers.  This version is experimental, and for recent CURRENT
only.

This version currently corresponds to Linux 5.0 DRM drivers, and should give
better support for more recent Intel and AMD GPUs.

Please note that this port is copied from drm-current-kmod, rather than
resurrected from the old drm-devel-kmod port, that's because
drm-current-kmod was created by copying the old drm-devel-kmod when that
went to a more stable version.

Big thank you to everyone who has worked on this, and johalun in particuar,
who has done most of the heavy lifting.

+The experimental drm-devel-kmod port can be enabled for amdgpu (for AMD
+GPUs starting with the HD7000 series / Tahiti), radeonkms for older AMD GPUs
+or i915kms (for Intel APUs starting with HD3000 / Sandy Bridge, possibly even
+older) through kld_list in /etc/rc.conf.

+For amdgpu and radeonkms, there have been reports of issues when using UEFI

+hw.syscons.disable=1  to /boot/loader.conf . Please note that this will
+disable the console until the graphics driver is loaded.

+Please ensure that all users requiring graphics are members of the

+Older generations are supported by the legacy kms modules by installing
+graphics/drm-legacy-kmod.
