[Libva] [PATCH] Downgrade the alignment requirement for linear surface on BDW+

[Zhao Yakui]

When sharing the YUY2/UYVY buffer with other driver, the current alignment is too
strict, which causes that it is not handled correctly by other driver.(The current
alignment is considered based on I420/YV12)
