50ac69eaa5 dcp: Wait 25ms after enabling dcp/dptx-phy power-domains
Fixes display initialization from stage 1 m1n1. 20ms looked reliable on
j473 but let's add 25% safety margin. Someone with more motivation (and
HW serial) to do repeated `kmutil configure-boot ...` can try to
minimize this and test on t602x.

187e7f8893 kboot/gpu: Add "no-map" property for reserved memory nodes

EFI memory map with the wrong type. This results in Linux mapping it

31ee1499f8 display: Support the HDMI output on M2* desktop systems
On M2* desktop systems the HDMI output is not managed by dcp/dcp0. This
allows more flexibility, for example dcp on the M2 Mac mini can be
routed to the USB-C/ThunderBolt ports.
For m1n1 this adds quite ab bit of complexity. In addition to the DCP
iboot endpoint/protocol two additional endpoints have to be started.
Only the dptx-port endpoint has a meaningful AP <=> DCP communication.
In addition we start the system endpoint to optionally enable more
verbose syslog messages (if RTKIT_SYSLOG is defined).
In addition the dptx-phy or lpdptx-phy has to be programmed. Those two
phy look mostly identical. MacOS seems to use a static DP configuration
(4 lanes, HBR3*) regardless of the connected display.
The added SMC gpio support is used to power the MCDP29xx DP to HDMI
converter on.
Config  is unfortunately a mess since Apple can't name the device tree
nodes consistently. On M2 Ultra devices only the four dcpext*/dispext*
on each die are used. M2 Ultra support is untested.

* link rate might differ on t602x based devices for 8k60 support

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.
