drm/i915/guc: Keep the ctx_pool_vaddr mapped, for easy access
The GuC descriptor is big in size. If we use a local definition of
guc_desc we have a chance to overflow stack, so avoid it.
Also, Chris abhors scatterlists :)
v2: Rebased, helper function to retrieve the context descriptor,
s/ctx_pool_vma/ctx_pool/
v3: Zero out guc_context_desc before initialization
v4: Do not do arithmetic on void pointers (Daniele)
v5: Nicer than arithmetic on pointers (Chris, Joonas)
