Maxim Anisimov 0128d860a0 ramips: dts: mt7628an: reset FE and ESW cores together
Failing to do so will cause the DMA engine to not initialize properly
and fail to forward packets between them, and in some cases will cause
spurious transmission with size exceeding allowed packet size, causing a
kernel panic.

Fixes: 60fadae62b ("ramips: ethernet: ralink: move reset of the esw into the esw instead of fe")
