Add the prototype to dump ip registers
for all ips of different asics and set
them to NULL for now. Based on the
requirement add a function pointer for
each of them.

Enable redirection of irq for pagefaults for specific
clients to avoid overflow without dropping interrupts.
So here we redirect the interrupts to another IH ring
i.e ring1 where only these interrupts are processed.

We need IH ring1 for handling the pagefault
interrupts which are overflowing the default
ring for specific usecases.

There is no reason to call return at the end of function that
returns void.
Fixes the below:
WARNING: void function return statements are not generally useful
Thus remove such a statement in the affected functions.

Retry faults are delegated to soft IH ring and then processed by
deferred worker. Current soft IH ring size PAGE_SIZE can store 128
entries, which may overflow and drop retry faults, causes HW stucks
because the retry fault is not recovered.
Increase soft IH ring size to 8KB, enough to store 256 CAM entries
because we clear the CAM entry after handling the retry fault from soft
ring.
Define macro IH_RING_SIZE and IH_SW_RING_SIZE to remove duplicate
constant.
Show warning message if soft IH ring overflows with CAM enabled because
this should not happen.
