While the CDB Assist and QcomLT Debugboard is measuring voltage and
current on the DC jack directly in the backend, other backends and
further measurements can be performed using custom tooling.
Introduce support for invoking an external "status-cmd" to produce such
status updates.
The status command should on its stdout produce json-formatted status
updates following the same format as the cdba-server:
{"ts":%d.%03d, "name": {["mv"|"ma"]: %u}(, "name2": {["mv"|"ma"]: %u})*}
with the ts aquired using clock_gettime(CLOCK_MONOTONIC) and provided in
seconds and milliseconds since the first measurement.

Now local_gpio has landed, also accept a more verbose
and cleaner yaml config syntax for ftdi_gpio.
For now keep support for the current configuration string.

Some devices / hubs require switching both USB-2 and USB-3 ports to
function correctly. Add ppps3_path device option to control USB-3 port
in addition to the USB-2 port.

This driver permits controlling local (on the system) gpios
by using the libgpiod library.
Support for gpiod v1 and v2 is added, and parses the options
via the yaml parser.
This can be tested with the gpio-sim module:

Control the board using external program. It will be called with 3
arguments: <board> <command> <on/off>, where command is one of "power",
"usb", "key-fastboot", "key-power".

Separate backend operations into control and console operations. Main
idea is that each device has single set of console ops (conmux or
console) and at most one way to control it. Each backend driver exports
a structure with the set of callbacks.

Since Linux kernel 6.0, PPPS capable USB hubs expose a simple sysfs

to use PPPS hub control instead.

For different reasons it might be desirable to keep slot 'b' as an
active slot. Add support for specifying the active slot in the config
file. The default is still slot 'a'.

Allow the control device to implement things such as flushing the
command buffer as part of the close operation. This used to be done to
ensure that any lingering power/usb off requests really where sent to
the device as we closed the control tty.

All modern systems will properly populate /dev/serial/by-id with links
to the CDB Assist control and target tty, that includes the serial
number in the name.
So there's no reason to keep the complex code that scans for the two
devices by serial number around.
Switch the parameter of "cdb_assist" to be the path of the control tty
and rely on "console" for the "terminal" tty.
Naturally this breaks existing config files.

It seems more suitable to use the "control_dev" to denote the target
conmux than "cdb_serial". Further more this makes it possible drop the
"cdb_serial" member in an upcoming commit.
