[PATCH 5.14 187/432] net: ipa: fix IPA v4.11 interconnect data

From: Greg Kroah-Hartman

[ Upstream commit 0ac26271344478ff718329fa9d4ef81d4bcbc43b ]

Currently three interconnects are defined for the Qualcomm SC7280
SoC, but this was based on a misunderstanding. There should only be
two interconnects defined: one between the IPA and system memory;
and another between the AP and IPA config space. The bandwidths
defined for the memory and config interconnects do not match what I
understand to be proper values, so update these.
