net: ipa: implement MAX_READS_BEATS QSB data
Starting with IPA v4.0, a limit is placed on the number of bytes
outstanding in a transaction, to reduce latency. The limit is
imposed only if this value is non-zero.
We don't use a non-zero value for SC7180, but newer versions of IPA
do. Prepare for that by allowing a programmed value to be specified
in the platform configuration data.
