A reasonably common operation is to pin the map of the vma alongside the
vma itself for the lifetime of the vma, and so release both pins at the
same time as destroying the vma. It is common enough to pull into the
release function, making that central function more attractive to a
couple of other callsites.
The continual ulterior motive is to sweep over errors on module load
aborting...

GuC related exported functions should start with "intel_guc_" prefix and
pass intel_guc as the first parameter since its GuC related. Current
guc_ggtt_offset() failed to follow this code convention and this is a
problem for future patches that needs to access intel_guc data to verify
the GGTT offset against the GuC WOPCM top.
This patch renames the guc_ggtt_offset to intel_guc_ggtt_offset and updates
the related code to pass intel_guc pointer to this function call, so that
we can have a unified coding style for GuC code and also enable the future
patches to get GuC related data from intel_guc to do the offset
verification. Meanwhile, this patch also moves the GUC_GGTT_TOP from
intel_guc_regs.h to intel_guc.h since it is not GuC register related
definition.
v8:
- Fixed coding style issues and moved GUC_GGTT_TOP to intel_guc.h (Sagar)
- Updated commit message to explain to reason and motivation to add
intel_guc as the first parameter of intel_guc_ggtt_offset (Chris)
v9:
- Fixed code alignment issue due to line break (Chris)
v10:
- Removed unnecessary comments, redundant code and avoided reuse variable
to avoid potential issues (Joonas)
v13:
- Updated the ordering of s-o-b/cc/r-b tags (Sagar)

The Additional Data Struct (ADS) contains objects that are required by
GuC post FW load and are not necessarily submission-only. Even with
submission disabled we may require something inside the ADS, so it
makes more sense for them to be always created.
Similarly, we need to access GuC logs and even if GuC submission
is disabled, to debug issues with GuC loading or with whatever we're using
GuC for.
v2: re-wording commit message (Sagar)
