[PATCH 07/11] drm/xe/xe2hpg: Remove extra allocation of CCS pages for dgfx

[Balasubramani Vivekanandan]

From: Akshata Jahagirdar <akshata.jahagirdar at intel.com>

In case of discrete platforms of Xe2_HPG, we don't need to handle
copying flat ccs metadata during eviction and restore.  So, remove the
extra allocation of ccs_pages.
