The patch series makes OA buffer size configurable by adding
a new property DRM_XE_OA_PROPERTY_OA_BUFFER_SIZE. With this
OA buffer size would now be configurable between 128KB and
128MB.

The patch series also takes care of the respective register bits
required to enable >16MB buffer size and removes hardcoded instances
of OA buffer size.

Note that a link to the UMD patch using this property would be posted
in the coming up revisions.
