The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

Current code actually does not set MODE1_SLEEP bit because the new value for
bitmask (0x1) is wrong. To set MODE1_SLEEP bit, we should pass MODE1_SLEEP
as the new value for bitmask.

Some drivers don't set the .owner fields of the struct device_driver or
struct pwm_ops, which causes the module usage count to become wrong.

Add pwm driver for the NXP pca9685 16 channel pwm-led controller.
The driver is really barebones at this stage. E.g. the OE' pin and
therefore the corresponding registers are not supported.
The driver was tested on a HW where this pin is tied to GND.
