01824a5767 ARM: dts: Fix gpmc regression for omap 2430sdp smc91x
Commit f4d809ec55b6 ("ARM: dts: Fix gpmc timings for omap 2430sdp")
added GPMC timings for 2430sdp. This however broke the Ethernet
for some versions of u-boot using a different L3 clock frequency:

set_gpmc_timing_reg: GPMC error! CS5: cs_rd_off: 233 ns, 39 ticks > 31
omap-gpmc 6e000000.gpmc: failed to set gpmc timings for: ethernet

This is because the smsc91x timings from 1.1.4 u-boot overflow the
GPMC registers when booted with 1.1.3 version of u-boot.

Let's fix this issue by using the better timings from u-boot 1.1.3
as they also work on 1.1.4 and are faster.

Note that so far the attempts over the years to calculate the GPMC
timings on the SDP boards have failed probably because of the
unknown latencies added by the FPGA on the debug boards.

1bb3740439 ARM: dts: Add smc91x GPMC configuration for 2430sdp
Let's use the bootloader values except for the partially configured
wait-pin that does not seem to work.

04a25dfb79 ARM: dts: Add basic device tree support for omap2430 sdp
I doubt that there are many people using 2430 sdp, but as
that's been historically an important acid test platform
for omap2+ related changes, let's add minimal device
tree support for it.

If anybody is using it beyond minimal boot testing, patches
for more complete device tree support are welcome.
