[Buildroot] [PATCH] configs/nitrogen8mp: update device trees list

[Gary Bisson]

- remove the A0 device tree as this (pre-prod) version of the CPU isn't
supported any longer
- add '-m4' variant to enable remoteproc api to Cortex-M core
- add ENC variants for our ENC carrier [1] (+ 1 with tc358743 support)

This fixes the build of the kernel for this board as the a0 dtb doesn't
exist any more. But I couldn't find any report of the defconfig failing,
are those still built regularly?

This patch replaces the previous one from my colleague [1].

Reagrds,
Gary
