Dmitry and I discussed in #freedreno to instead add the INTF_BLK_DSI_TE
macro that accounts for the INTF TE registers using this higher register
area, as well as an extended signature to configure extra interrupts.

(Besides, I think the len is currently only used for snapshot dumping
and no validation for out-of-blk reads/writes)
