mfd: max77686: Fix regmap resource leak on driver remove
commit 74142ffc0b52cfe6f9d2f6f34a5f3eedbfe3ce51 upstream.
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.
