regulator: max77686: fix gpio_enabled shift wrapping bug
commit c53403a37cf083ce85da720f18918f73580d0064 upstream.
The code should handle more than 32 bits here because "id"
can be a value up to MAX77686_REGULATORS (currently 34).
Convert the gpio_enabled type to DECLARE_BITMAP and use
test_bit/set_bit.
Fixes: 3307e9025d29 ("regulator: max77686: Add GPIO control")
