[Intel-gfx] [PATCH v2] drm/i915/icl: Update forcewake firmware ranges

[Radhakrishna Sripada]

Some workarounds are not sticking across suspend resume cycles. The
forcewake ranges table has been updated and would reflect the hardware
appropriately.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1222

v2: Simplify the table and use 0 for some unused ranges(Matt)
