[ Upstream commit 0fd75f5760b6a7a7f35dff46a6cdc4f6d1a86ee8 ]
Three interconnects are defined for IPA version 4.9, but there
should only be two. They should also use names that match what's
used for other platforms (and specified in the Device Tree binding).

net: ipa: don't index mem data array by ID2021-06-10T21:50:08ZAlex Elder2021-06-10T19:23:08Zurn:sha1:c61cfb941dcd8c0529a0c0be31bb1722feaa6082
Finally the code handles the IPA memory region array in the
configuration data without assuming it is indexed by region ID.
Get rid of the array index designators where these arrays are
initialized. As a result, there's no more need to define an
explicitly undefined memory region ID, so get rid of that.
Change ipa_mem_find() so it no longer assumes the ipa->mem[] array
is indexed by memory region ID. Instead, have it search the array
for the entry having the requested memory ID, and return the address
of the descriptor if found. Otherwise return NULL.
Stop allowing memory regions to be defined with zero size and zero
canary value. Check for this condition in ipa_mem_valid_one().
As a result, it is not necessary to check for this case in
ipa_mem_config().
Finally, there is no need for IPA_MEM_UNDEFINED to be defined any
more, so get rid of it.

net: ipa: store memory region id in descriptor2021-06-09T22:59:33ZAlex Elder2021-06-09T22:34:54Zurn:sha1:14ab6a208c11dcb7b91fda3e0866c7e6188dc553
Store the memory region ID in the memory descriptor structure. This
is a move toward *not* indexing the array by the ID, but for now we
must still specify those index values. Define an explicitly
undefined region ID, value 0, so uninitialized entries in the array
won't use an otherwise valid ID.
