media: dt-bindings: nokia,smia: Amend SMIA bindings with MIPI CCS support

Browse source 
Amend the existing SMIA bindings by adding MIPI CCS support, with separate
compatible strings for CCS 1.0 and CCS 1.1. Rename the old bindings
accordingly as CCS is the current standard.

CCS (Camera Command Set) is a raw Bayer camera sensor standard defined by the
MIPI Alliance; see

SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension of
that. These definitions are valid for both types of sensors.
