ezsp to ember migration

[ALERTua]

As Zigbee2MQTT states in its logs, ezsp support will be soon dropped in favor of ember. Koenkk/zigbee2mqtt#21462

[2024-05-18 11:44:24] warning: 	zh:ezsp: Deprecated driver 'ezsp' currently in use, 'ember' will become the officially supported EmberZNet driver in next release. If using Zigbee2MQTT see https://github.com/Koenkk/zigbee2mqtt/discussions/21462

Are there any plans for this migration in XiaomiGateway3 @AlexxIT ?

Check this #1328 and this #1307

Only problem is ember needs latest firmware. I don't have the skill to build them. And don't have time to update the compiled firmware in the integration.

Thank you. Maybe you should keep this issue to update users on the progress of this. Hoping for the best.

Unfortunately as per Koenkk/zigbee-herdsman#943 (comment) EFR32MG1B (Xiaomi Multimode Gateway) is not going to be supported, as EFR32MG1B does not support recent versions of the NCP firmware. However, the RCP firmware works perfectly on EFR32MG1B. You can try convincing the zigbee-herdsman folks to reconsider their stance on the RCP firmware.

I will soon compile a firmware for Xiaomi Multimode Gateway 2 that supports the ember driver.

I have updated my repo at https://github.com/zalatnaicsongor/MGLGWFW/tree/main/mg21 with some newly compiled binaries for the Xiaomi Multimode Gateway 2 + uploaded some binaries to help with the flashing of the firmware to https://github.com/zalatnaicsongor/MGLGWFW/tree/main/arm

Once I find some time, I will update the flashing script to do the flashing automatically + maybe raise a PR in this repo to automate the process completely.

In the meantime I'm trying to look at fixing the bugs that cause the ember driver to fail with the RCP firmware + zigbeed.
