regmap: Updates for v4.21

Browse source 
This has been a busy release for the regmap-irq code, there's several
 new features been added, including an API cleanup for how we specify
 types that affected one existing driver (gpio-max77620):
 
  - Support for hardware that flags rising and falling edges on separate
    status bits from Bartosz Golaszewski.
  - Support for explicitly clearing interrupts before unmasking from
    Bartosz Golaszewski.
  - Support for level triggered IRQs from Matti Vaittinen.
