[PATCH v5 0/7] More missing XeLP workarounds

[Tvrtko Ursulin]

Some more missing XeLP workarounds. This time including some which need to go
into indirect context, which also means some plumbing had to be added.

Includes a fix to use iosys helpers for existing wa bb emission since there is a
code dependency on it.

v2:
 * Use iosys helpers.
 * Split indirect context plumbing as a separate patch.
 * Tweak where and how Wa_16010904313 is emitted.
 * Move Wa_18022495364 into the wa_bb.

 v3:
 * Rewrite on top of Lucas' wa bb changes - use same infrastructure.

v4:
 * Rework due 3a1edef8f4b5 ("drm/xe: Make WA BB part of LRC BO").

v5:
 * Fix indirect ring state offset calculation.
 * Removed extra space in one patch.
