Subject: [PATCH v4 09/27] mfd: Add new driver for MAX77705 PMIC

Add the core MFD driver for max77705 PMIC. We define five sub-devices
for which the drivers will be added in subsequent patches.

Signed-off-by: Dzmitry Sankouski <dsankouski@...il.com>

---
Changes for V4:
- rework driver from scratch
- migrate to regmap_add_irq_chip, remove max77705-irq.c,
  rename max77705-core.c to max77705.c
- cleanup headers
- remove debugfs code
- migrate to use max77693_dev structure
- remove max77705.h
