For cuImage format it's necessary to provide clock fixups since u-boot will
not pass necessary clock frequency into the dtb included into cuImage so we
implement the clock fixups as defined in the technical documentation for the
board and update header file with the basic register definitions.

This patch adds support for the ESTeem 195E Hotfoot SBC.
There are several variants of the SBC deployed, single/dual
ethernet+serial, and also 4MB/8MB flash variations. In the interest of
having a single kernel image boot on all boards, the cuboot shim detects
the differences and mangles the DTS tree appropriately.
With the exception of the CF interface that was never populated on
production boards, this code/DTS supports all boardpop options.

- Add gpio-controller node for BCSR17, it is used to control USB
speed and VBUS;
- Add timer node for QE GTM, needed for USB host;
- Add usb node itself;
- Add some probing code for BCSR GPIOs.
NOTE: QE USB doesn't work on prototype boards, but should work on
pilot boards if specs and schematics are correct, though we
don't have the pilot boards to actually test it.

This patch simply adds sdhci node to the device tree.
We specify clock-frequency manually, so that eSDHC will work without
upgrading U-Boot. Though, that'll only work for default setup (1500
MHz) on new board revisions. For non-default setups, it's recommended
to upgrade U-Boot, since it will fixup clock-frequency automatically.

The earlier mpc8560 CPUs don't have the RSTCR at 0xe00b0

Allows interrupts to occur on the sbc834x. Currently PCI devices
get assigned an incorrect IRQ and so the interrupt count never
increases. This was tested with the 82546GB based dual port E1000

Actually, the support is already there, but it requires newer U-Boots
(to fill-in clock-frequency, and setup pin multiplexing).
Though, it appears that on RDB boards USBB pins aren't multiplexed
between USB and eSDHC (unlike MDS boards, where USB and eSDHC share
pctl and pwrfault pins).
So, for RDB boards we can safely setup pinmux and manually fill-in
clock-frequency, thus making eSDHC work even with older u-boots.

Sometimes (e.g. when there are no UEMs attached to a board)
fsl_pq_mdio_find_free() fails to find a spare address for a TBI PHY,
this is because get_phy_id() returns bogus 0x0000ffff values
(0xffffffff is expected), and therefore mdio bus probing fails with
the following message:
fsl-pq_mdio: probe of e0082120.mdio failed with error -16
And obviously ethernet doesn't work after this.
This patch solves the problem by adding tbi-phy node into mdio node,
so that we won't scan for spare addresses, we'll just use a fixed one.

usb0 and usb1 mux settings in the sicrl register were swapped (twice!)
in mpc834x_usb_cfg(), leading to various strange issues with fsl-ehci
and full speed devices.
The USB port config on mpc834x is done using 2 muxes: Port 0 is always
used for MPH port 0, and port 1 can either be used for MPH port 1 or DR
(unless DR uses UTMI phy or OTG, then it uses both ports) - See 8349 RM
figure 1-4..
mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit
positions of the usb0 / usb1 mux settings swapped. It would basically
work if you specified port1 instead of port0 for the MPH controller (and
happened to use ULPI phys), which is what all the 834x dts have done,
even though that configuration is physically invalid.
Instead fix mpc8349_usb_cfg() and adjust the dts files to match reality.
