We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.
Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

powerpc/mpic: FSL MPIC error interrupt support.
All SOC device error interrupts are muxed and delivered to the core
as a single MPIC error interrupt. Currently all the device drivers
requiring access to device errors have to register for the MPIC error
interrupt as a shared interrupt.
With this patch we add interrupt demuxing capability in the mpic driver,
allowing device drivers to register for their individual error interrupts.
This is achieved by handling error interrupts in a cascaded fashion.
MPIC error interrupt is handled by the "error_int_handler", which
subsequently demuxes it using the EISR and delivers it to the respective
drivers.
The error interrupt capability is dependent on the MPIC EIMR register,
which was introduced in FSL MPIC version 4.1 (P4080 rev2). So, error
interrupt demuxing capability is dependent on the MPIC version and can
be used for versions >= 4.1.

powerpc/85xx: remove P1020RDB and P2020RDB CAMP device trees
We only need two examples of CAMP device trees in the upstream kernel.
Co-operative Asymmetric Multi-Processing (CAMP) is a technique where two
or more operating systems (typically multiple copies of the same Linux
kernel) are loaded into memory, and each kernel is given a subset of the
available cores to execute on. For example, on a four-core system, one
kernel runs on cores 0 and 1, and the other runs on cores 2 and 3.
The devices are also partitioned among the operating systems, and this is
done with customized device trees. Each kernel gets its own device tree
that has only the devices that it should know about.
Unfortunately, this approach is very hackish. The kernels are trusted to
only access devices in their respective device trees, and the partitioning
only works for devices that can be handled. Crafting the device trees is a
tricky process, and getting U-Boot to load and start all kernels is
cumbersome.
But most importantly, each CAMP setup is very application-specific, since
the actual partitioning of resources is done in the DTS by the system
designer. Therefore, it doesn't make a lot of sense to have a lot of CAMP
device trees, since we only expect them to be used as examples.

When attaching an imx28 or imx53 in USB gadget mode to a Windows host and
starting a rndis connection we see this message every 4-10 seconds:
g_ether gadget: high speed config #2: RNDIS
Analysis shows that each time this message is printed, the rndis connection is
re-establish due to a reset because of a stalled endpoint (ep 0, dir 1). The
endpoint is stalled because the reqeust complete bit on that endpoint is set,
but in isr_tr_complete_low() the endpoint request list (mEp->qh.queue) is
empty.
This patch removed this check, because the code doesn't take the following
situation into account:
The loop over all endpoints in isr_tr_complete_handler() will call ep_nuke() on
both ep0/dir0 and ep/dir1 in the first loop. Pending reqeusts will be flushed
and completed here. There seems to be a race condition, the request is nuked,
but the request complete bit will be set, too. The subsequent check (in
ep0/dir1's loop cycle) for endpoint request list (mEp->qh.queue) empty will
fail.

* If CPU hotplug cycles happen back-to-back before workers finish the
previous cycle, the states could get out of sync and it could get
stuck. Fixed by waiting for workers to complete before finishing
hotplug cycle.
* While CPU hotplug is in progress, idle workers could be depleted
which can then lead to deadlock. I think both happening together
is highly unlikely but still better to fix it and the fix isn't too
scary.
