Lionel Landwerlin cd956bfcd0 drm/i915/perf: add a parameter to control the size of OA buffer 
The way our hardware is designed doesn't seem to let us use the
MI_RECORD_PERF_COUNT command without setting up a circular buffer.

In the case where the user didn't request OA reports to be available
through the i915 perf stream, we can set the OA buffer to the minimum
size to avoid consuming memory which won't be used by the driver.

v2: Simplify oa buffer size exponent selection (Chris)
    Reuse vma size field (Lionel)

v3: Restrict size opening parameter to values supported by HW (Chris)

v4: Drop out of date comment (Matt)
    Add debug message when buffer size is rejected (Matt)
