ARM: SMDK6410: Add nC1 chipselect SROM setup

Since the mach-smdk6410.c file claims it can start up the
smsc9115 ethernet device on the board, it should take care
about configuring the necessary chip select nCS1 so it can
see the chip.  The select defaults to 8-bit mode so without
config the Ethernet doesn't work.

This patch uses the new SROM definitions to set nCS1 to the
state found in the Samsung U-Boot port for 6410.  It may be
more conservative that it needs to be since those settings
were marked as for CS8900A also using this chip select.

But this change is enough to get the ethernet working when
booted with Qi.
