9c80a69266 m1n1.hv: Use dynamic pin maps in trace_gpio.py 
Hardcoded pin maps do not make sense with additional HW support.
Allows tracing of a single pin in another tracing module, for example
for tracing the SPI cs pin.

6a8016a8e3 experiments/dcp.py: set DVA offset from ADT 
This does not appear to be necessary. It worked on t8103 before and I
see no different behavior on t6001.

66f4d625b8 experiments/dcp.py: Use t8103/t600x specific code paths 
MMIO space differes between t8103 and t600x so the hardcoded RegMonitor
addresses make only sens on the former.
set_display_device difference is taken from macOS trace on t6001.

4575b35479 rust: Initial Rust-based EFI FAT32 chainloader 
This code is gated behind the CHAINLOADING define. To build a
release-style m1n1 with chainloading for use with the installer
or kmutil, use:

make CHAINLOADING=1 RELEASE=1

To tell m1n1 to chainload another binary, use this var payload:

chainload=<ESP partition UUID>;<file path>

e.g.

chainload=a17b7e46-e950-bb4f-bc82-8ab1047a058e;m1n1/m1n1.bin

Closes: #154
