ARM: ux500: Disable SMSC911x platform code registration when DT is enabled

Now the SCMC911x is correctly enabled in Device Tree, there is no need
to continue registering it from platform code. In fact, if we continue
doing so, the system will throw an error on boot.

ARM: ux500: Remove DB8500 PRCMU platform registration when DT is enabled

Now the DB8500 has Device Tree support it will be probed when the DT
is parsed, rendering the requirement for platform registration void.
This patch removes DB8500 PRCMU platform registration.

ARM: ux500: Re-enable SMSC911x platform code registration during non-DT boots

The patch to disable SMSC911x registration was applied twice in the upstream
kernel by mistake. Git interpreted this as 'take the same entry from a
similar struct' which was close by. This was the wrong thing to do. This patch
rectifies this error and re-enables SMSC911x registration when Device Tree is
not enabled.

ARM: ux500: Use correct format for dynamic IRQ assignment

This patch applies the correct format requested by the irq
domain. For chained IRQs which use GPIO lines as IRQs, we
stipulate that a two cell request is required. The first cell
contains the requested IRQ and the second can contain flags
pertaining to edge detection and level sensitive values. The
zeroth cell specifies the GPIO controller by use of a phandle.

ARM: ux500: Disable platform setup of the ab8500 when DT is enabled

The final piece of the ab8500 puzzle. Here we prevent any of the ab8500-*
drivers from being registered from platform code when Device Tree is
enabled, as we expect DT do probe each of these individually. We also
provide the relevant compatible strings, so that DT knows which nodes
it needs to pay attention to during population.

ARM: ux500: Only initialise STE's UIBs on boards which support them

ST-Ericsson uses User Interface Boards to extend functionality of
some of their development boards. However, these aren't compatible
with all the supported boards found in Mainline (Snowball for
instance). This patch ensures that the UIBs are only probed on
boards which can actually support them. This in turn saves lots of
unnecessary error messages normally found in Snowball's boot log.

This patch adds the function nfsd4_encode_components_esc() to
allow the caller to specify escape characters when splitting on 'sep'.
In order to fix referrals, this patch must be used with the mountd patch

rpc: handle rotated gss data for Windows interoperability

The data in Kerberos gss tokens can be rotated.  But we were lazy and
rejected any nonzero rotation value.  It wasn't necessary for the
implementations we were testing against at the time.

But it appears that Windows does use a nonzero value here.

So, implement rotation to bring ourselves into compliance with the spec
and to interoperate with Windows.
