On some STMicroelectronics hardware reside regulators consisting
partly of a PWM input connected to the feedback loop. As the PWM
duty-cycle is varied the output voltage adapts. This driver
allows us to vary the output voltage by adapting the PWM input
duty-cycle.

Remove checking control_reg in [set|get]_voltage_sel and then convert to use
regulator_[set|get]_voltage_sel_regmap for [set|get]_voltage_sel callbacks.
The anatop-reg-offset property is a required property rather than optional
property. So the question is what is the meaning of setting anatop-reg-offset
to 0? If 0 is a valid setting for anatop-reg-offset and it has special meaning,
we had better document it in the binding document. Otherwise, remove the testing
for control_reg in the driver.
No anatop voltage regulator node in the dts files set anatop-reg-offset to 0.
So I think it's safe to remove testing if control_reg is 0.

This patch extends the regulator helpers to account for device that use
multiple bits for control when using regmap enable/disable/bypass ops.
The actual regulator helpers wrongly assume that the regulator control
is always performed using single bits, using in the regulator_desc
struct only two parameters *_reg and *_mask defining register and mask
for control.
This patch extends this struct and introduces the helpers to take into
account devices where control is performed using multiple bits and
specific multi-bit values are used for enabling/disabling/bypassing the
regulator.
