ARC: mcip: update MCIP debug mask when the new cpu came online
[ Upstream commit f3205de98db2fc8083796dd5ad81b191e436fab8 ]
As of today we use hardcoded MCIP debug mask, so if we launch
kernel via debugger and kick fever cores than HW has all cpus
hang at the momemt of setup MCIP debug mask.
So update MCIP debug mask when the new cpu came online, instead of
use hardcoded MCIP debug mask.
