[PATCH v2 2/4] dt-bindings: mfd: lp87565: convert to yaml

[Luca Ceresoli <luca@lucaceresoli.net>]

The definition of "xxx-in-supply" was generic, thus define in detail the
possible cases for each chip variant.

Also document that the only possible I2C slave address is 0x60 as per the
datasheet and fix the second example accordingly.

Changes in v2:
 - this patch replaces patch "regulator: lp87565: dt: remove duplicated
   section" in RFC,v1 (Rob Herring)
 - use capital letters consistently (Lee Jones)
 - replace "regulator" -> "mfd" in subject line (Lee Jones)
 - replace "dt:" suffix with "dt-bindings:" prefix in subject line
