This fixes bug introduced in 667a6b7a (regulator: max14577: Add missing
of_node_put). The DTS parsing function returned number of matched
regulators as success status which then was compared against 0 in probe.
Result was a probe fail after successful parsing the DTS:
max14577-regulator: probe of max14577-regulator failed with error 2

Remove the "struct max14577_regulator" because this is not used
anywhere. It should be removed earlier along with changing the driver
after review on the mailing lists.

MAX14577 chip is a multi-function device which includes MUIC,
charger and voltage regulator. The driver is located in drivers/mfd.
This patch adds regulator driver for MAX14577 chip. There are two
regulators in this chip:
1. Safeout LDO with constant voltage output of 4.9V. It can be only
enabled or disabled.
2. Current regulator for the charger. It provides current from 90mA up
to 950mA.
Driver supports Device Tree.
