Subject: [PATCH] Fixes Adreno 400 slow performance.

Adreno 300 and 400 have the same video driver performance issues because they are very similar architectures which use basically the same thing with
everything.
There isn't any need to detect the family of the driver with Qualcomm anyway. If we ever need family specific bugs then we can implement real support
for that.
Performance issue on Adreno 400 series was due to us only detecting Adreno 300 series, and with Adreno 400 it wouldn't use the bugs, which would cause
it to use glBufferSubData, causing the huge performance hit.
