regulator: tps6586x: add PFM/PWM options on SMs supply
TPS6586x SM0, SM1 and SM2 port have 2 power switching modes:
- PWM only, or
- PMW-PFM auto mode
Some of TPS6586x have voltage spike in PFM-to-FWM transition can lockup
the CPU if choose PWM-PFM auto mode.
This patch enables such mode selection on SMs ports from the board level
power configuration file.
