Fix these unwanted behaviors:
- With kernel >= v6.3 /dev/colibri-watchdog-som and /dev/colibri-watchdog
are missing. Driver init sequence changes, the KERNEL label changes
from watchdog to watchdog1 and relevant rule that create the symlinks
stops matching.
- With kernel < v6.3 /dev/colibri-watchdog-som and /dev/colibri-watchdog-soc
are pointing to the same device, respectively /dev/watchdog0 (miscdev)
and /dev/watchdog (cdev) using the same watchdog device
(the SoM rn5t618 watchdog). Instead, it is expected that
/dev/colibri-watchdog-soc links to the SoC imx2-wdt watchdog device.
These are the current two configurations:
< v6.3:
/dev/colibri-watchdog -> watchdog0 (rn5t618)
/dev/colibri-watchdog-soc -> watchdog1 (imx2-wdt)
/dev/colibri-watchdog-som -> watchdog0 (rn5t618)
>= v6.3:
/dev/colibri-watchdog -> watchdog1 (rn5t618)
/dev/colibri-watchdog-soc -> watchdog0 (imx2-wdt)
/dev/colibri-watchdog-som -> watchdog1 (rn5t618)

Depending on the kernel driver probe time in some circumstances the udev
event is not add, but change, add both to the rules. Without this change
the uart symlinks are not created if the imx-sdma driver is loaded after
udev is started.

commit a6d094403cd6 ("ARM: dts: imx: Change usdhc node name on i.MX6/i.MX7 SoCs")
commit bffe02ccca5b ("ARM: dts: imx: make wdog node name generic")
```
in kernel source has changed the `usdhc`, `watchdog` node names, adapt
the udev rules to match both the old and new naming scheme.

ENV{DEVTYPE} has been found to not be present on apalis-imx6 sometimes.
Since we see also some troubles on our lava setup this property is being
removed from this rule as anyway disk and partition is already catched with the
"p" in the KERNEL rule

recipes-core: udev: change sd-card symlinks to style of emmc rules
This commit does three things:
- Use "-part<number>" instead of "-p" as it is with /dev/emmc symlinks
- Use ENV{DEVTYPE} as it is used with /dev/emmc symlinks to for sure
be able to distinguish partitions vs. disks
- Use %n in stead of $attr{partition} as it is already used for emmc
symlink rules

Create symlinks for each supported by Colibri iMX7/iMX7-eMMC
ADC channels, standardizing names as colibri-ainX, according
to the Colibri signal names table.

According to the internal document "Hardware interfaces
standardization", the UART interfaces should be accessed
via device nodes named with the module family and matching
the signal name used in the module datasheet.
Modify udev rules for UART devices accordingly.

These rules make sure that a symlink is created for all i2c and tty
devices. This symlinks are named like on the Toradex carrier boards.
This makes it easy to identify which device in software is matching
the hardware pins.
Additional non-standard devices that are not named clearly on the
carrier board are left out to prevent confusion.
