pvr: Replace sub_cmd flags with bools within each sub_cmd type.

This commit remove:
 - PVR_SUB_COMMAND_FLAG_TRANSFER_SERIALIZE_WITH_FRAG.
 - PVR_SUB_COMMAND_FLAG_OCCLUSION_QUERY.

The first flag was specific to transfer sub commands and the last
one, for graphics ones. Now we just have a bool in the transfer
sub_cmd, and one in the graphics sub_cmd.
