Draft: arm: dts: imx93: update heartbeat gpio

A wrong GPIO was specified in U-Boot device tree for heartbeat LED for iMX93. Actualized the configuration by analogy with Linux.

But this MR does not enable a corresponding LED driver in U-Boot config, so it won't flash.

Note: both iMX8MP and iMX8MM designs are affected by this issue (on iMX8MM, this LED is LIT on power on).

Hello @fschrempf

as this MR has not been handled, let me use it to provide patches which enable a LED support in U-Boot.

After U-Boot will be rebuilt, LED functionality will be accessible via "led" command.
Here is an example on how to view available LEDs, then to turn hearbeat LED on, off and then toggle it two times:

=> led list
led1            <inactive>
=> led led1 on
=> led led1 off
=> led led1 toggle
=> led led1 toggle 

deleted the feature/v2024.01-ktn/mx93 branch. This merge request now targets the v2024.01-ktn branch
