drm/ttm: Fix TTM BO accounting
TTM BO accounting is out of sync with how memory is really allocated
in ttm[_dma]_tt_alloc_page_directory. This resulted in excessive
estimated overhead with many small allocations.
ttm_dma_tt_alloc_page_directory makes a single allocation for three
arrays: pages, DMA and CPU addresses. It uses drm_calloc_large, which
uses kmalloc internally for allocations smaller than PAGE_SIZE.
ttm_round_pot should be a good approximation of its memory usage both

drm: Switch blobs to the new generic modeset obj refcounting
Need to move the free function around a bit, but otherwise mostly
just removing code.
Specifically we can nuke all the _locked variants since the weak idr
reference is now protected by the idr_mutex, which we never hold
anywhere expect in the lookup/reg/unreg functions. And those never
call anything else.
Another benefit of this is that this patch switches the weak reference
logic from kref_put_mutex to kref_get_unless_zero. And the later is in
general more flexible wrt accomodating multiple weak references
protected by different locks, which might or might not come handy
eventually.
But one consequence of that switch is that we need to acquire the
blob_lock from the free function for the list_del calls. That's a bit
tricky to pull off, but works well if we pick the exact same scheme as
is already used for framebuffers. Most important changes:
- filp list is maintainer by create/destroy_blob ioctls directly
(already the case, so we can just remove the redundant list_del from
the free function).
- filp close handler walks the filp-private list lockless - works
because we know no one else can access it. I copied the same comment
from the fb code over to explain this.
- Otherwise we need to sufficiently restrict blob_lock critical
sections to avoid all the unreference calls. Easy to do once the
blob_lock only protects the list, and no longer the weak reference.

drm: Add support of ARC PGU display controller
ARC PGU could be found on some development boards from Synopsys.
This is a simple byte streamer that reads data from a framebuffer
and sends data to the single encoder.

The driver supports now a second platform and received several

drm/fsl-dcu: use variable name dev for struct drm_device
The driver uses different variable names for struct drm_device
across functions which is confusing. Stick to the more common
variable name dev. While at it, remove unnecessary if statement
in error handling.

drm/fsl-dcu: handle missing panel gracefully
If the device tree property fsl,panel is missing, drm_panel_attach
is called with a NULL pointer as first argument. Having a panel is
basically mandatory since RGB is the only supported connector.
Check if a panel node has been found, return -ENODEV and cleanup
otherwise.

drm/layerscape: reduce excessive stack usage
The fsl-dcu driver copies a drm_mode_config object to its
stack but then only accesses a single member (dpms_property)
once. The data structure is large enough to trigger a warning
about the amount of kernel stack being used:
drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_rgb.c: In function 'fsl_dcu_drm_connector_create':
drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_rgb.c:182:1: error: the frame size of 1040 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
This changes the fsl_dcu_drm_connector_create() function to
only access the drm_mode_config by reference, which is also
more efficient.
