46c945ac95 usb: use dynamic paths for usb related ADT nodes 
Adds support for the 3rd USB-C port on 2021 Macbook Pros.
Currently up to 8 USB-C ports are supported which should be sufficient
for expected future devices.

Tested on Macbook Pro 14" and Mac Mini.

407663b73d bootstrap_port: Improve UART baud setting 
Rework the serial port bootstrap so it works correctly if the target is already
at 1500000 baud.

No baud adjustment is made if the proxy is using the serial-USB interface.

Tested with the Mac-to-Mac serial connection (macvdmtool) and the serial-USB
connection.

anything, but it does make this sysreg trap performance-critical,

1d932888f9 Add command categories to reduce command clutter 
Based on a suggestion from Ludwig Schubert it now uses the inspect class
to generate signatures of the functions for the help messages and
the qualified names which is a big improvement.

Also greatly reduced the clutter by putting the class functions into seperate
categories based on their class name. Now the top level help fits on one
page making it much more readable.

98076ef693 usb: disable tps6598x interrupts 
Restore the interrupt masks on chainload or HV guest start. The
interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
line.
