lantiq: fix boot isues on danube boards
Enabling SMP on Danube[1] is incompatible with a patch that
adds support for interrupt handling on all cores on other
platforms[2]. This patch fixes the mentioned issue.
1. 084c20f6c54180f2dc6b3efc1c5ba9b62afbaf26 ("lantiq: xway: kernel: enable SMP support ")
2. fbd33d61648ae8982fbada7ad3b6d8222b367ab5 ("lantiq: enable interrupts on second VPEs")
Fixes: #13934
Fixes: #14283
