drm/msm/adreno: Allow larger address space size
The restriction to 4G was strictly to work around 64b math bug in some
versions of SQE firmware. This appears to be fixed in a650+ SQE fw, so
allow a larger address space size on these devices.
Also, add a modparam override for debugging and igt.
v2: Send the right version of the patch (ie. the one that actually
compiles)
