drm/xe/debugfs: Add dump of default LRCs' MI instructions
For non-RCS engines, nearly all of the LRC state is composed of MI
instructions (specifically MI_LOAD_REGISTER_IMM). Providing a dump
interface allows us to verify that the context image layout matches
what's documented in the bspec, and also allows us to check whether LRC
workarounds are being properly captured by the default state we record
at startup.
For now, the non-MI instructions found in the RCS and CCS engines will
dump as "unknown;" parsing of those will be added in a follow-up patch.
v2:
- Add raw instruction header as well as decoded meaning. (Lucas)
- Check that num_dw isn't greater than remaining_dw for instructions
that have a "# dwords" field. (Lucas)
- Clarify comment about skipping over ppHWSP. (Lucas)
