hwmon: (max1619) Convert to use regmap

Use regmap for local caching, to hide register read/write address
differences, and for multi-byte operations. With this change,
the driver specific lock is no longer necessary.

While at it, check errors seen when initializing the chip and bail out
if chip initialization fails.
