Akhil P OommenandGreg Kroah-Hartman bad87bdd52 drm/msm/a6xx: Use barriers while updating HFI Q headers 
[ Upstream commit dc78b35d5e ]

To avoid harmful compiler optimizations and IO reordering in the HW, use
barriers and READ/WRITE_ONCE helpers as necessary while accessing the HFI
queue index variables.
