drm/msm: a6xx: fix version check for the A650 SQE microcode
I suppose the microcode version check for a650 is incorrect. It checks
for the version 1.95, while the firmware released have major version of 0:
0.91 (vulnerable), 0.99 (fixing the issue).
Lower version requirements to accept firmware 0.99.
Fixes: 8490f02a3ca4 ("drm/msm: a6xx: Make sure the SQE microcode is safe")
