drm/xe/debugfs: Dump register save-restore tables

Browse source

Add debugfs entry to dump the final tables with register save-restore
information.

For the workarounds, this has a format a little bit different than when the
values are applied because we don't want to read the values from the HW
when dumping via debugfs. For whitelist it just re-uses the print
function added for when the whitelist is being built.
