Liang Chen cf8b87bbec sched: optimize prio for kernel RT thread and kworker 
In some cases, there are too much userspace high priority RT threads, which
cause kernel RT threads or kworkers block too long time. This config separate
kernel and userspace RT threads into two priority regions, priority 0~49 for
kernel and priority 50~99 for userspace, so that kernel RT threads is always
higher priority than userspace. This config also set RT policy for kworkers.
