b9ddd74c02 hv/trace_smc.py: Add SMC tracer 
Also fix up a bunch of stuff in m1n1.fw.smc, but it's untested as a
client.

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.

b15be6bcd7 Remove hardcoded UART/WDT addresses 
The M1 Pro/Max Macs use a different base address for the UART and the
WDT than earlier models.

Remove hardcoded base addresses constants and replace them with loads
from the ADT.

- The base address of the WDT is already retrieved in wdt_disable; also
use this address when triggering a reboot.
- Retrieve the base address of uart0 in uart_init. If the operation
fails, the error will be signaled on the early uart (if not disabled).
- The early debug UART can’t use the ADT (or shouldn’t) so it is now
disabled by default. To enable it, add
-DEARLY_UART -DEARLY_UART_BASE=0xuart_address
to the CFLAGS.
