panfrost: Add empty tile flags to GenXML

These flags control special CRC handling for empty tiles using the CRC
clear colour field added on Bifrost. Their use depends on CRC being
used. We missed these flags earlier; let's add them since they are used
by the Valhall DDK but are not new to Valhall.
