This patchset depends on this patchset[1] and this patch[2] which adds support
for polarity control in imx-pwm driver.
- Use pwm polarity control on iMX7 based modules.
- Enable polarity control on Toradex Colibri iMX7D/S module.
- Add BL_ON GPIO control for Toradex Colibri iMX7D/S module.

This patchset actually depends on the v6 patchset[1] from Lothar.
Some how that patchset got stalled in ML. I will re-spin the v6
patchset with the suggestions/changes from Lukasz in this patch[2]
after testing.
