[Media Common] Enable Wa to disable object capture for DG1

[nyanmisaka]

This Wa is needed for using DG1 with the upstream i915 kernel.

Partially fixes:
#1415 (comment)

The other part needs to be fixed on KMD side by disabling HCP_POWERGATE and MFXVDENC_POWERGATE for DG1. Unlike TGLx, DG1 doesn't support sub-pipe PG and setting these bits will cause HEVC and VP9 decoding failure.

@Jexu Inspired by the regression in Xe KMD, I'm sure the above will work together to make DG1 usable in upstream i915.

Linux 6.13+ and LTS releases (6.1.124+, 6.6.70+ and 6.12.9+) have included the DG1 powergate fix.

@Jexu @XinfengZhang
So can we merge this to end the long-standing issues on DG1 when using upstream version of i915 KMD?

---

Also, if I understand correctly, the MEDIA_WR_SKU(skuTable, FtrGucSubmission, 1) flag should also be enabled.

The kernel 5.16+ enables GuC submission on DG1 by default, just like it does on ADL-P/ADL-N+.

Hi @XinfengZhang, could you spare a minute to merge this simple fix?

DG1 is now available in both i915 & Xe KMD in upstream linux. See also #1920
