mfd: max77686: Fix regmap resource leak on driver remove
The regmap used by max77686 MFD driver was not freed with regmap_exit() on driver exit. This lead to leak of resources. Replace regmap_init_i2c() call in driver probe with initialization of managed register map so the regmap will be properly freed by the device management code.
