The syscon node has an incorrect notation for its unit address and the
wdt node has an unneeded unit address.

Fix them so that the following build warnings with W=1 are gone:

arch/arm/boot/dts/imx51-ts4800.dtb: Warning (unit_address_vs_reg): Node /soc/aips@80000000/weim@83fda000/fpga@0/syscon@b0010000/wdt@e has a unit name, but no reg property

The following build warning is seen with W=1:

Warning (unit_address_vs_reg): Node /display-di0/port@0 has a unit name,
but no reg property

Fix this warning by removing '@' from such node.

Contrary to later i.MX SoCs, the parallel display interface pad groups on
i.MX51 are called DISP1 and DISP2 in the Reference Manual, not DISP0 and
DISP1.

Fix this inconsistence by changing the DISP names in the i.mx51 dts.

Replace the non-standard vendor prefix stm with st for
STMicroelectronics. The drivers do not specify the vendor prefixes
since the I2C Core strips them away from the DT provided compatible
string. Therefore, changing existing device trees does not have any
impact on device detection.

Enable FPGA's IRQ controller. It is in charge of dispatching interrupts
generated by IPs in the FPGA. The SoC is notified that an interrupt
occurred through a GPIO.

Previously, the device tree mapped the FPGA like any other IPs inside
the SoC, but it is actually mapped through the WEIM (Wireless External
Interface Module). This patch updates the device tree to make use of it.

About the timings: in the image provided by the manufacturer, only
CS0GCR1 is changed. The other values are the default ones, but the WEIM
bindings expect them to be all explicitly set in the device tree, so I
just put the default values in the dt.

This device tree adds support for TS-4800 by Technologic Systems. This
board is based on MX51-babbage, but there are some subtle differences in
the pins used, and there is an additional FPGA that is memory-mapped.
