73b78abe3b afk: epic channel/interface numbers do not reset

hold a service for every possible channel but keep a fixed array of 8

76fbc77ad2 afk: Prepare afk/epic for handling of multiple endpoints 
This needs to ensure that the data processing does not block on
message retrieval from the mailbox. Command processing must not block
and have to ensure that afk_epic_command() receives the reply to its
command.
DCP's dptx-port endpoint (endpoint 0x2a) can send notifies at any time
which needs to be processed in the right context.

fecfa130e9 kboot: Parse "anvram" partition start and size from ADT 
"nvram" size depends on the iboot version. Monterey (12.3) and earlier

size to 1M. Parse the values from the ADT and fill and enable the node

24a3a0d962 kboot: Move MCC cache enable to kboot 
Following the general "do more in stage2/kboot, do less in stage1/proxy"
rule. In case something goes wrong here we want to be able to fix it in
stage2.

Thanks to the stupid bug, the past year+ of stage1 installs has had this
codepath disabled, so that works well with this change.
