In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

The struct voltage_map_desc is used for storing min/max/step fileds, and
then setup the min_uV, uV_step and n_voltages fields for regulator_desc.
Introduce MAX8998_LINEAR_REG/MAX8998_OTHERS_REG macro to setup these filds
directly in regulator_desc to simplify the code.

At the context with rdev, we can use rdev->regmap instead of mcp->rmap.
The *rdev[NUM_REGULATORS] is not required because current code uses
devm_regulator_register() so we don't need to store *rdev for clean up
paths.

Providing a range for usleep_range() allows the hrtimer subsystem to
coalesce timers - as this delay has no upper limit anyway (interrupts
or context switch is possible) it should not hurt to extend this
from 2 to 2-4 milliseconds.
