clk: max77686: Combine Maxim max77686 and max77802 driver

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. Part of common code utilisation, there is 3 files for these chips clock driver, one for common and two files for driver registration. Combine both drivers into single file and move common code into same common file reduces the 2 files and make max77686 and max77802 clock driver in single fine. This driver does not depends on the parent driver structure. The regmap handle is acquired through regmap APIs for the register access. This combination of driver helps on adding clock driver for different Maxim PMICs which has similar clock IP like MAX77620 and MAX20024.
