Freescale CoreNet-based and Non-CoreNet-based platforms require
different PM operations. This patch extracted existing PM operations
on Non-CoreNet-based platforms to a new file which can accommodate
both platforms. In this way, PM operation codes are clearer structurally.

There is a RCPM (Run Control/Power Management) in Freescale QorIQ
series processors. The device performs tasks associated with device
run control and power management.
The driver implements some features: mask/unmask irq, enter/exit low
power states, freeze time base, etc.

Various e500 core have different cache architecture, so they
need different cache flush operations. Therefore, add a callback
function cpu_flush_caches to the struct cpu_spec. The cache flush
operation for the specific kind of e500 is selected at init time.
The callback function will flush all caches inside the current cpu.

On e6500, in the case of cpu hotplug, either thread in one core
may be the first thread initilzing the TLB1. The subsequent threads
must not setup it again.
The code is derived from the comment of Scott Wood.
