This patch adds device tree documentation for the sbs-manager

+From OS view the device is basically an i2c-mux used to communicate with up to

+batteries. Channels will be numerated as 1, 2, 4 and 8.

+batman@0a {

+    reg = <0x0a>;
+    sbsm,i2c-retry-count = <3>;
+    #address-cells = <1>;
+    #size-cells = <0>;
+
+    channel1@1 {

channel@1

Do we have a standard node name for mux nodes? If not, we should.

No name is enforced by the i2c mux support code, but I think "i2c"
dominates, and quite possibly it is the only documented name?
