msm: kgsl: Make VBIF register dump more generic
Make VBIF register dump more generic to avoid adding new entry
for every VBIF revision. There will not be any change in register
mapping and address for new VBIF revision. AHB reads are permitted
throughout entire VBIF range. For all unoccupied registers read
values driven to 0 by HW but should not be relied upon.
