[Intel-gfx] [PATCH] Revert "drm/i915: Initialize HWS page address after GPU reset"

[Arun Siluvery]

This reverts commit 2e5356da370e36ba7aab39d2800c7a2412630ae7.

It is now redundant as it is already covered in below commit which introduced
the changes to reuse initialization of resources in resume/reset path.

    drm/i915: Split alloc from init for lrc

lrc_setup_hardware_status_page() in the same function gen8_init_common_ring()
takes care of this.
