Subject: [PATCH 0/2] rpmsg: glink: Wait for intent after intent request

When written it was assumed that upon requesting an intent, the intent
would arrive followed by an intent request acknowledgement. But this is
not always the case, in which case the current implementation would
request yet another intent and when that is acknowledged find the first
received intent - if the remote didn't run out of memory and failed the
second request...
