drm/xe/oa/uapi: Make OA buffer size configurable
Add a new property called DRM_XE_OA_PROPERTY_OA_BUFFER_SIZE to
allow OA buffer size to be configurable from userspace.
With this OA buffer size can be configured to any power of 2
size between 128KB and 128MB and it would default to 16MB in case
the size is not supplied.
v2:
- Rebase
v3:
- Add oa buffer size to capabilities [Ashutosh]
- Address several nitpicks [Ashutosh]
- Fix commit message/subject [Ashutosh]
