[PATCH 2/3] drm/i915/gt: Relocate Gen7 context-specific workarounds

[Sebastian Brzezinka]

The workarounds for disabling Render Cache Operational Flush and
PIXEL_SUBSPAN_COLLECT_OPT_DISABLE were previously applied in
rcs_engine_wa_init(). These are specific to Gen7 platforms
so move them to gen7_ctx_workarounds_init() for better alignment with
platform-specific initialization.
