Martí Bolívar 51f55b437f twister: replace dt_compat_enabled_with_alias filter 
Originally added in 7733b94224.

This filter is not well-formed. It's meant to match nodes like
/leds/led_0 in this DTS:

/ {
	aliases {
		led0 = &led0;
	};

	leds {
		compatible = "gpio-leds";
		led0: led_0 {
			gpios = <...>;
			label = "LED 0";
		};
	};
};

Uses look like this:

    filter: dt_compat_enabled_with_alias("gpio-leds", "led0")

But notice how the led_0 node doesn't have compatible "gpio-leds";
it's actually the *parent* node that has that compatible.

Replace this with a new filter, dt_enabled_alias_with_parent_compat(),
which is used like this:

    filter: dt_enabled_alias_with_parent_compat("led0", "gpio-leds")

This has a name and argument order that makes the meaning of the
filter clearer.

Replace in-tree users with the new filter.

Deprecate the old filter and warn about its use using the standard
logging module.

Open Supervised Device Protocol (OSDP)
######################################

Open Supervised Device Protocol (OSDP) is an IEC standard (IEC 60839-11-5)
intended to improve interoperability among access control and security products.
It supports Secure Channel (SC) for encrypted and authenticated communication
between configured devices.

OSDP describes the communication protocol for interfacing one or more Peripheral
Devices (PD) to a Control Panel (CP) over a two-wire RS-485 multi-drop serial
communication channel. Nevertheless, this protocol can be used to transfer
secure data over any stream based physical channel. Read more about `OSDP here
<https://libosdp.gotomain.io/>`_..

Although OSDP is steered towards the Access and Security industries, it can be
used as a general communication protocol for devices in a secure way without
too much resource requirements. The security is not top-notch (AES-128) but it
is reasonable enough, given that the alternative is no security at all.

OSDP Supports the control of the following components on a PD:
   - LED
   - Buzzer
   - Keypad
   - Output (GPIOs)
   - Input Control (GPIOs)
   - Displays
   - Device status (tamper, power, etc.,)
   - Card Reader
   - Fingerprint Reader
