drm/xe: Correct BMG VSEC header sizing

Browse Source 
The intel_vsec_header information for the crashlog feature is
incorrect.

Update the VSEC header with correct sizing and count.

Since the crashlog entries are "merged" (num_entries = 2), the
separate capabilities entries must be merged as well.
