Subject: qed: Fix Config attribute frame format.
Patch-mainline: v5.4-rc1
Git-commit: 2da244a5c4b5fdbb5ae6cc89f85421defed59a5b
References: jsc#SLE-8401

MFW associates the entity id to a config attribute instead of assigning
one entity id for all the config attributes.
This patch incorporates driver changes to link entity id to a config id
attribute.

Fixes: 0dabbe1bb3a4 ("qed: Add driver API for flashing the config attributes.")
