cxgbe(4): Expanded interrupt handling for T7HEADmain

- Catch up with the new cause/perr registers.  The high level approach
  is the same but the T7 has an extra top level INT_CAUSE concentrator
  and a PERR_CAUSE concentrator with a changed layout.

- Add various flags to control the interrupt handlers' behavior.

- Implement a t4_intr_clear that internally use the slow handler as an
  iterator over known cause/perr registers.  This lets the driver clear
  all of the interrupt sources that it knows about.  The firmware sets
  up the interrupt enables and clears the causes normally so this call
  should be redundant.
