[PATCH v3 04/15] mfd: max14577: Add "muic" suffix to regmap and irq_chip

[Krzysztof Kozlowski]

This patch continues the preparation for adding support for max77836
device to existing max14577 driver.

Add "muic" suffix to regmap and irq_data fields in maxim_core state
container to prepare for max77836 support.
This is only a rename-like patch, new code is not added.
