ARM: ux500: Enable probing of pinctrl through Device Tree

The Nomadik GPIO controller now relies on Nomadik pinctrl, however
the pinctrl driver is not currently started by any ux500 platform.
This is requred or GPIOs do not work at all.

Though actually this doesn't matter much, as NFSv4.0 clients are

nfsd: add IPv6 addr escaping to fs_location hosts

The fs_location->hosts list is split on colons, but this doesn't work when
IPv6 addresses are used (they contain colons).
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
that similarly fixes IPv6 [] escaping.

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.

SUNRPC: new svc_bind() routine introduced

This new routine is responsible for service registration in a specified
network context.

The idea is to separate service creation from per-net operations.

Note also: since registering service with svc_bind() can fail, the
service will be destroyed and during destruction it will try to
unregister itself from rpcbind. In this case unregistration has to be
skipped.

SUNRPC: move per-net operations from svc_destroy()

The idea is to separate service destruction and per-net operations,
because these are two different things and the mix looks ugly.

Notes:

1) For NFS server this patch looks ugly (sorry for that). But these
place will be rewritten soon during NFSd containerization.

2) LockD per-net counter increase int lockd_up() was moved prior to
make_socks() to make lockd_down_net() call safe in case of error.

sunrpc: do array overrun check in svc_recv before allocating pages

There's little point in waiting until after we allocate all of the pages
to see if we're going to overrun the array. In the event that this
calculation is really off we could end up scribbling over a bunch of
memory and make it tougher to debug.

This function creates service if it doesn't exist, or increases usage

This is just a code move, which from my POV makes the code look better.
I.e. now on start we have 3 different stages:
1) Service creation.
2) Service per-net data allocation.
3) Service start.

NFSD: SETCLIENTID_CONFIRM returns NFS4ERR_CLID_INUSE too often

According to RFC 3530bis, the only items SETCLIENTID_CONFIRM processing
should be concerned with is the clientid, clientid verifier, and
principal.  The client's IP address is not supposed to be interesting.

And, NFS4ERR_CLID_INUSE is meant only for principal mismatches.

I triggered this logic with a prototype UCS client -- one that
uses the same nfs_client_id4 string for all servers.  The client
mounted our server via its IPv4, then via its IPv6 address.
