i915g: Advertise PIPE_CAP_BUFFER_MAP_PERSISTENT_COHERENT

Browse Source 
Currently buffer_map returns the raw pointer, there is no syncing or
flushing or staging buffers or resource shadowing anywhere. That means
if the driver is currently correct, it is implementing persistent and
coherent behaviour already, so the CAP is trivial.
