The msm provides timer hardware that is private to each core. Each
timer has separate counter and match registers, so we create separate
clock_event_devices for each core. For the global clocksource, use
cpu 0's counter.

SCM is the protocol used to communicate between the secure and
non-secure code executing on the applications processor. The
non-secure side uses a physically contiguous buffer to pass
information to the secure side; where the buffer conforms to a
format that is agreed upon by both sides. The use of a buffer
allows multiple pending requests to be in flight on the secure
side. It also benefits use cases where the command or response
buffer contains large chunks of data.

  init_task_group_load --> root_task_group_load

Now that all prerequisites are in place, drop the two-stage driver
instances initialization in favor of the following simple init sequence:

1. Probe PCI device: we only test ECC capabilities here and if none exit
early.

2. If the hw supports ECC and it is/can be enabled, we init the per-node
instance.

There actually should be no visible functional change resulting from
this patch.
