ENGR00174974 [MX6]Fix CPU hotplug platform related issue

We need to turn of cache coherency of secondary core before
it is disable by core0, otherwise, the secondary core may be
waked by cache sync, and if it exit from wfi and access BUS,
meanwhile, core0 disable it from hardware, the whole SOC would
hang.
