This compatible property was documented before the driver was renamed to
"SBS" (see commit e57f1b68c406 ("devicetree-bindings: Propagate
bq20z75->sbs rename to dt bindings")). The driver has continued to
support this property as an alternative to "sbs,sbs-battery", and
because we've noticed there are some lingering TI specifics (in the
manufacturer-specific portion of the SBS spec), we'd like to start using
this property again to differentiate.
In typical DT fashion, the <vendor>,<part-number> specifics should be
used ahead of the generic "sbs,sbs-battery" string, so we can handle
vendor specifics -- so document this. Language borrowed mostly from
Documentation/devicetree/bindings/power/supply/sbs_sbs-charger.txt
Also fixup the example to use this property (it's already implying that
it's "bq20z75@b"); fixup the node name to be generic ("battery", not
"<part-number>"); and fixup some whitespace.

v2: add Rhyland's Acked-by
v3: no change
v4: add Rob's Reviewed-by
v5:
* note "sbs,sbs-battery" as a fallback for vendor,part-number
* improve the Example
* I still kept the {Acked,Reviewed}-by, since the substance of the
change is essentially the same. Apologies if that is not proper.
