Subject: [PATCH 2/5] clk: Combine DT binding doc for max77686 and max77802
The clock driver for Maxim PMICs max77686 and max77802 are
combined into single file to extend the support for same clock
IP for different PMICs.
Remove the separate DT binding document file for maxim,max77802 and
move all information to maxim,max77686 DT binding document.
