mfd: max77759: Improve static struct formatting and commentary

Improve code style. This includes the following:
- Formatting the max77759_chgr_irqs entries to fit in a single line
  instead of breaking them into multiple lines to improve readability.

- Refactoring comments such that they're full sentences and have
  punctuation marks for a couple of macro definitions to adhere to the
  documentation style.

- Explicitly initializing `MAX77759_CHGR_MODE_OFF`.
