Update to SPF11.4.CSU1

This commit is the application of a diff between SPF11.1.CSU1 and
SPF11.4.CSU1 over the existing qca-wifi-oss repo.

The only conflicts were caused by QSDK moving a few files over to
qca-wifi-host-cmn that we had changes in; those changes have been
re-applied to that repo and we've removed the files in this repo.
