The "compatible" property description contradicts even the example given:
it only says that there must be a single value while the example has the
fallback value too -- which makes much more sense. Moreover, the generic
property value is misdocumented as being R-Car (and RZ/G1) specific...

This patch is against Linus' repo -- the 'fixes' branch in Thierry Reding's
'linux-pwm.git' repo is very outdated...
Changes in version 2:
- fixed the wording of the fallback value description.
