x86/cpu/intel_epb: Don't rely on link order
intel_epb_init() is called as a subsys_initcall() to register cpuhp
callbacks. The callbacks make use of get_cpu_device() which will return
NULL unless register_cpu() has been called. register_cpu() is called
from topology_init(), which is also a subsys_initcall().
This is fragile. Moving the register_cpu() to a different
subsys_initcall() leads to a NULL dereference during boot.
Make intel_epb_init() a late_initcall(), user-space can't provide a
policy before this point anyway.
