Port 0 carries the N1 as on J716c: the boot loader trains the link, the platform ID is 0x46050 and the Wi-Fi and Bluetooth functions are on DART streams 1-3. The GPU, its reservations and both GPU mailboxes follow the J714s layout and stay disabled until the loader enables them. Signed-off-by: Joshua Warren <816217+joshuaswarren@users.noreply.github.com>
The boot loader fills the N1 factory Wi-Fi and Bluetooth addresses through the wifi0 and bluetooth0 aliases. Without them the interface has the all-zero address. Signed-off-by: Joshua Warren <816217+joshuaswarren@users.noreply.github.com>

Thanks Joshua. The N1 on port 0 and the GPU handoff dtsi follow the J716c/J714s layout, everything new stays disabled until the loader turns it on, and the wifi0/bluetooth0 aliases fix the all-zero MAC. Only t6050-k114c files change, so no other board's DTB moves. DT checks pass.

The 14-inch M5 Max MacBook Pro (K114c) has no Wi-Fi and no GPU in the tree today. This adds both to
t6050-k114c.dts.gpio-reserved-rangesexposes only pin 80 (PERST#).t6050-k114c-gpu.dtsidescribes the GPU, its reserved memory and both GPU mailboxes in the J714s layout. They stay disabled until the loader enables them.wifi0andbluetooth0aliases let the boot loader write the factory Wi-Fi and Bluetooth addresses. Without them the interface comes up with the all-zero address.Tested on a 14-inch M5 Max MacBook Pro: Wi-Fi associates and carries ssh, and the loader fills in the GPU node and the GPU driver probes it.
Bluetooth: the function enumerates (106b:1903) but no driver binds yet, so it does not work.
Opened as a draft. The GPU needs the mailbox change in #1601 and the firmware identification in #1602 (on #1173) before it starts.
