eaddr is sometimes treated as the last address inside the address
range, and sometimes as the first address outside the range. This
was resulting in errors when a test filled up the entire address
space. Make it consistent to always be the last address within the
range.

This adds EDC support for CZ.
EDC = Error Correction and Detection
This code properly initializes the EDC hardware and
resets the error counts. This is done in late_init
since it requires the IB pool which is not initialized
during hw_init.

Read the vbios directly from the rom. In some cases,
e.g., virtualization, the rom is not available via
the BAR or other means. Access it directly.
This is an updated version of Monks original patch which
uses family specific callbacks and unifies some of the
validation checking.

Here's the first drm-misc pull, with really mostly misc stuff all over.
Somewhat invasive is only Ville's change to mark the arg struct for
fb_create const - that might conflict with a new driver pull. So better to
get in fast.

I noticed that intel_fbdev->our_mode is unused. Introduced by
79e539453b ("DRM: i915: add mode setting support").
Then I noticed that intel_fbdev->fbdev_list is unused as well.
Introduced by 386516744b ("drm/fb: fix fbdev object model +
cleanup properly.") in i915, nouveau and radeon.
Subsequently cargo culted to amdgpu, ast, cirrus, qxl, udl,
virtio and mgag200.
Already removed from the latter with cc59487a05 ("drm/mgag200:
'fbdev_list' in 'struct mga_fbdev' is not used").
Remove it from the others.
