Some wifi-related functionality was enabled on ccimx93 overrides. The
ccimx91 also needs this functionality but it was not being applied as
the overrides were only for ccimx93.
Generalize the overrides for ccimx9.

There are some cases in which the loading of the Wi-Fi modules may be
problematic due to timing conditions:
- when a suspend operation in progress is aborted
- when Bluetooth is disabled
The Wi-Fi needs some time for the system to be ready before loading the
modules.
This commit:
- Stops the Bluetooth before bringing down the Wi-Fi on suspend
- Starts the Bluetooth (or adds a small delay) before bringing up the
Wi-Fi on resume
- Reworks the way the resume operations are programmed, to do them in
reverse order (first load the Wi-Fi modules, then bring the interfaces
up (if required). It does so by appending/prepending actions into a
variable and dumping the contents finally to a temp file.

When switching off the 3.3V supply from the Wi-Fi during suspend,
around a 10% of the times, when resuming the Wi-Fi driver fails to load.
It was verified that a rebind operation over the mmc interface (which
eventually calls the script that loads the Wi-Fi module) makes it
load successfully, which denotes a timing issue during resume.
Adding a small delay on the resume operation before running the script
makes the Wi-Fi driver load at the first try.

This allows to set RTC configuration parameters. For example, the rv3028
RTC included in ccmp1 and ccimx93 has the "backup switching mode"
configuration in a register that is saved to an eeprom. By default the
BSM value is 00, which means backup switchover disabled. This means that
even if you connect a coin cell to our DVK, the RTC will ignore it.
With this commit, the BSM can be configured to direct switching mode
(DSM) or level switching mode (LSM) so the RTC uses the battery when the
device is powered off.

The btnxpuart driver uses internally the serial port to manage the chip, and
loads the BT FW independently of the WiFi subsystem.
While on it, add support in the bluetooth-init script to be able to power the

We need to take in account if the IW612 chip (WiFi/Bt) is going to be powered
off on suspend state. In such a case, we need to unload the driver modules and
restore the expected tty speed for Bluetooth, so that functionality is restored
back on resume.

The following files were duplicated across platforms but were
identical or almost identical.
Only used on SysVinit (currently only by default on the CC6UL).
- standby
- acpid.map
Only used on SystemD
- standby-actions
Notes:
- The triggering of udev actions are harmless if the interfaces
don't exist.
- The value of KEY_POWER on acpid.map for CC6/CC6Plus was originally
0 instead of 1, but this file is not currently used in systemd.

Even though our busybox recipe (v1.34.1) is backported from poky's honister
branch, it has many elements in common with the recipe provided from poky's
hardknott branch (v1.33.1). To simplify our backport, re-use poky's busybox
files when possible, replacing them only when strictly necessary.
While at it, remove the busybox-inittab recipe, since there are barely any
differences between the honister and hardknott versions.

Some packages require different scripts, configuration files or installations
depending on the wireless chip assembled on the target. In general, the way
to support both chips in one image is to have the recipes install both
versions of the aforementioned files, then leave only the strictly necessary
version once the wireless chip can be deduced.
In the case of the init-ifupdown recipe, this involves installing temporary
configuration fragments that are later erased. In the case of the standby
script, the logic can be implemented in a single file.

This script behaves the same way as our custom standby script, with a few
modifications, for example:
* instead of using initscripts to stop/start daemons, it uses systemctl calls
* save variables that are needed when resuming in /tmp, because the script is
executed twice instead of once (when suspending and when resuming)
* remove the locking/unlocking of the critical section and the actual state
change, since that is handled by systemd-suspend now
Also, add a different standby script for when systemd is enabled. Said script
acts as a wrapper for systemd's suspend mechanism.
