dt-bindings: mfd: lp87565: Convert to yaml
Also apply a few smaller improvements:
- document that the only possible I2C slave address is 0x60 as per the
datasheet and fix the second example accordingly
- The definition of "xxx-in-supply" was generic, thus define in detail the
possible cases for each chip variant
- remove "MFD driver" from the title as it is implementation specific
- replace "PMIC" with "buck converter" in title as it is more informative
