Subject: [PATCH v4 2/5] drm/msm/adreno: Add speedbin data for SM8550 / A740

Add speebin data for A740, as found on SM8550 and derivative SoCs.

For non-development SoCs it seems that "everything except FC_AC, FC_AF
should be speedbin 1", but what the values are for said "everything" are
not known, so that's an exercise left to the user..
