[Feature]Pulse-Width Modulation enabling on Broxton-P

The following patches in 4.4 kernel implement this:
f080be2 pwm: lpss: Add support for runtime PM
03f00e5 pwm: lpss: Add more Intel Broxton IDs
87219cb pwm: lpss: Support all four PWMs on Intel Broxton
4e11f5a pwm: lpss: Add support for multiple PWMs
361c106 pwm: lpss: pci: Add support for Broxton platform

Add three patches in v4.5 for this:
3767067 pwm: lpss: Rework the sequence of programming PWM_SW_UPDATE
883e4d0 pwm: lpss: Update PWM setting for Broxton
c7b91b3 pwm: lpss: Remove ->free() callback

This bug was fixed in the package linux - 4.4.0-7.22
