Update GuC ADS size allocation to include space for
the lists of error state capture register descriptors.
Also, populate the lists of registers we want GuC to report back to
Host on engine reset events. This list should include global,
engine-class and engine-instance registers for every engine-class
type on the current hardware.
NOTE: Start with a sample table of register lists to layout the
framework before adding real registers in subsequent patch.

no, please don't cast/export struct guc_ads like this. We can't really
dereference it since it may be in IO memory.
See https://patchwork.freedesktop.org/series/99378/ with the huge
refactor in this file to make it conform to the rules of accessing IO
memory.
Maybe this list could be appended in the same reglist buffer and we just
copy it once to its final location, like we are doing with the reglist?
