The clock IP used on the Maxim PMICs max77686 and max77802 are
same. The configuration of clock register is also same except
the number of clocks.

Define the common DT binding file for the clocks of Maxim PMICs
MAX77686 and MAX77802. For this, remove the separate DT binding
document file for maxim,max77802 and move all information to
maxim,max77686 DT binding document.

Changes from V1:
- Rewrite description to remvoe ref to driver.
- Taken care of comment from Krzysztof on the supported clocks and
  DT bindings.

Changes from V2:
- Collected RBs.
