uart: allow UART_DEV_DBGPORT for fdt consoles
Allow fdt devices to be used as debug ports for gdb(4).
A debug console can be specified with the "freebsd,debug-path" property
in the device tree's /chosen node, or using the environment variable
hw.fdt.dbgport.
The device should be specified by its name in the device tree, for
example hw.fdt.dbgport="serial2".
