SYR82X is a regulator that supports two modes of operation:
- Auto-PFM: Allow automatic PFM during light load (default mode)
- Forced PWM

Some boards require to configure forced PWM mode from device tree to keep
the supply ripple within acceptable limits under light load conditions.

SYR82X is a clone of FAN53555 regulator and its configuration is handled by
the fcs,fan53555 driver. All clones of FAN53555 regulator share the same
two mode of operation (Auto-PFM / Forced PWM).

However the implementation in the driver is currently restricted to SYR82X
as it is the only tested hardware.

V1 -> V2:
  - Add missing dt binding property description
  - Naming changes since all clones handled by the fan53555 driver share
    the same two modes
      - dt binding header name changed from silergy,syr82x.h to 
        fcs,fan53555-regulator.h - dt binding header constants changed from
        SYR82X_* to FAN53555_* 
      - fan53555_silergy_map_mode() changed to fan53555_map_mode()
  - More detailed commit descriptions

V2 -> V3:
  - Remove garbage in commit description of first commit and duplicated
    SoB line
