This patch adds needed nodes and properties to support suspend/resume
on the MPC8610HPCD boards.

There is a dedicated switch (SW9) that is used to wake up the boards.
By default the SW9 button is routed to IRQ8, but could be re-routed
(via PIXIS) to sreset.

With 'no_console_suspend' kernel command line argument specified, the
board is also able to wakeup upon serial port input.

This patch adds suspend/resume support for MPC8540 and MPC8641D-
compatible CPUs. To reach sleep state, we just write the SLP bit
into the PM control and status register.

So far we don't support Deep Sleep mode as found in newer MPC85xx
CPUs (i.e. MPC8536). It can be relatively easy implemented though,
and for it we reserve 'mem' suspend type.

struct mcc defined in both immap_qe.h and immap_cpm2.h, so they will
conflic when included in a single file. The mcc struct is easy to deal
with, since it isn't used in any driver (yet), so let's just rename QE
version to qe_mcc.

The ucb_ctlr is a bit trickier, since it is used by fsl_qe_udc driver,
and the driver supports both CPM and QE UDCs, plus the QE version is
used to form a bigger immap struct.

I don't want to touch too much of USB code in this series, so for now
let's just copy most generic version into the common cpm.h header,
later we'll create cpm_usb.h where we'll place common USB structs that
are used by QE/CPM UDC and QE Host drivers (FHCI).

And as for the structs in qe.h and cpm2.h, just prefix them with qe_
and cpm_.

It is an e500 based dual core SOC.
Being a scaled down version of P2020 it has following differences from P2020:
- 533MHz - 800MHz core frequency.
- 256Kbyte L2 cache
- Ethernet controllers with classification capabilities(new controller).

For MPC8569 CPUs we'll need to reset QE after each suspend, so make
qe_reset() code path suitable for repeated invocation, that is:

- Don't initialize rheap structures if already initialized;
- Don't allocate muram for SDMA if already allocated, just reinitialize
  registers with previously allocated muram offset;
- Remove __init attributes from qe_reset() and cpm_muram_init();

core0 has memory, L2, i2c, spi, dma1, usb, eth0, eth1, crypto,

The PCI-e addressing was originally patterned of the MPC8548CDS
which has PCI1, PCI2, and PCI-e.  Since this board only has
PCI1 and PCI-e, it makes more sense to be similar to the MPC8568MDS
board.  This does that by cutting the PCI/PCI-e I/O sizes from
16MB to 8MB and pulling the PCI-e I/O range back to 0xe280_0000
(the hole where PCI2 I/O would have been).

This also fixes a typo where an extra zero made an 8MB range a 128MB
range, removes the hole left by PCI2 from the aliases, and sets the
clocks to match the oscillators that are actually on the board.

With accompanying u-boot updates, PCI-e has been validated with
both a sky2 card (1148:9e00) and an e1000 card (8086:108b).
