Add a VRAM carveout that is used for systems which do not have an IOMMU.
The VRAM carveout uses CMA. The arch code must setup a CMA pool for the
device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not
cool). The user can configure the VRAM pool size using msm.vram module
param.
Technically, the abstraction of IOMMU behind msm_mmu is not strictly
needed, but it simplifies the GEM code a bit, and will be useful later
when I add support for a2xx devices with GPUMMU, so I decided to keep
this part.
It appears to be possible to configure the GPU to restrict access to
addresses within the VRAM pool, but this is not done yet. So for now
the GPU will refuse to load if there is no sort of mmu. Once address
based limits are supported and tested to confirm that we aren't giving
the GPU access to arbitrary memory, this restriction can be lifted

`comedi_free_board_dev()` is called (via `comedi_auto_unconfig()` -->
`comedi_release_hardware_device()`) when an auto-configured comedi
device is removed. This destroys the main sysfs class device and then
calls `comedi_device_cleanup()` to clean up the comedi device. For
comedi devices that have comedi subdevices that asynchronous commands,
the clean up involves destroying the sysfs class devices associated with
those subdevices.
There is a bug in the above sequence because the sysfs class devices
associated with the comedi subdevices are children of the sysfs class
device associated with the main comedi device. Therefore they will have
been automatically destroyed when the main sysfs class device is
destroyed. When they are destroyed again as part of the clean-up, they
will not be found, leading to a warning and a stack trace similar to
this:
