The rust-analyzer generator script recognizes a crate when its
corresponding `.o` appears in the Rust source file's immediate `Makefile`
or `Kbuild` file.
Commit ca524e273c43 ("gpu: build nova-core and nova-drm from
drivers/gpu/Makefile") moves the build rules for `nova-core` and
`nova-drm` into `drivers/gpu/Makefile`, which results in the generator
script ignoring these crates.
Fix this by naming the crates' module as a comment in their respective
`Makefile`; this is enough for the script to pick them up and restore
`rust-analyzer` functionality on them.

A dependency between nova-core and nova-drm is about to be introduced,
which requires nova-core to be built first. As this is not easily doable
from separate directories, move both build targets to the first common
parent, `drivers/gpu/Makefile`.

Update nova/Makefile and nova-core/Makefile so that nova-drm.ko and
nova-core.ko are produced, matching the module names set in patch 1.
Update drm::DriverInfo with the correct driver name and vendor
description. Fix Kconfig help text for both drivers and the debugfs
directory name in nova-core to match the new module names.

Add the initial nova-drm driver skeleton.
nova-drm is connected to nova-core through the auxiliary bus and
implements the DRM parts of the nova driver stack.
For now, it implements the fundamental DRM abstractions, i.e. creates a
DRM device and registers it, exposing a three sample IOCTLs.
DRM_IOCTL_NOVA_GETPARAM
- provides the PCI bar size from the bar that maps the GPUs VRAM
from nova-core
DRM_IOCTL_NOVA_GEM_CREATE
- creates a new dummy DRM GEM object and returns a handle
DRM_IOCTL_NOVA_GEM_INFO
- provides metadata for the DRM GEM object behind a given handle
I implemented a small userspace test suite [1] that utilizes this
interface.
