The WARN_ON() was only checking the first clock in the array, instead of
being executed for each clksrc clock being registered.

Since this is an array of clocks, WARN_ON() does not provide a lot of
useful information about the problem, so change to using printk(KERN_ERR)
to report the problem to the console.

As a note, we still try and register the clock even if these problems are
present just in case and to avoid changing the behaviour of the registration
process.

Adds a additional check in s3c_set_clksrc function to ensure that the clksrc_clk
does have a choice of multiple clock sources. In addition to this, a check is
added to ensure that a parent is assigned to the clksrc_clk in case it does not
have a choice of parent clocks.

The clk_hd0 and clk_pd0 where given a local dummy_enable call due to
not being registered with the clock code, which they really should have
been. Register these two clocks and remove the clk_dummy_enable as this
is done by the default clock registration code.

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.

The new code calls the clock setup code on registration which
can be before the clock system has been fully initialised. The

registration and thus we get two printings.

the necessary resume work.
