Subject: [PATCH v6 01/23] mfd: max77686: Convert to use regmap_irq
By using the generic IRQ support in the Register map API, it
is possible to get rid max77686-irq.c and simplify the code.
Suggested-by: Krzysztof Kozlowski <k.kozlowski@...sung.com>

Changes since v5: None
Changes since v4:
- Remove left over defines not used anymore. Suggested by Krzysztof Kozlowski.
Changes since v3: None
Changes since v2:
- Cleanup regmap irqchips on i2c_driver .remove function.
Suggested by Doug Anderson.
- Remove unused MAX77686_IRQ_NR enum. Suggested by Doug Anderson.
