[PATCH v4 0/2] poweroff-source DT property renaming

[Auto Configured]

The goal of this serie is to rename the property "poweroff-source" to
"system-power-controller". After discussions, it makes more sense to rename back
to the old established property name. This patches serie reverts
commit a4b4e0461ec5 ("of: Add standard property for poweroff capability").

Changes since v3:
  - Move backward compatibility from of_is_system_power_controller to
    tps65910, as it was only required for this driver.

Changes since v2:
  - of_is_system_power_controller is inline in of.h and only supports
    backward compatibility with device drivers which used this helper
    (which is tps65910)
  - Quashed all changes into a single patch (except documentation)
  - Add a separated commit to fix typos and mispellings in documentation

Changes since v1:

  - The first patch defines "of_is_system_power_controller" which is compatible
    with both "vendor,system-power-controller" and "system-power-controller"
    properties. Also, It keeps the old helper function of_system_has_poweroff_source
    for source compatibility until everything is renamed (in this way, bisections
    are not broken and change is made "atomically" between each commit)

    Note: the property "poweroff-source" itself is not used in dts files yet.
    Before this patch tps65910 was broken due to missing backward compatibility
    with "vendor,system-power-controller". As the old helper uses the new one,
    it works again.

  - act8865 and tps65910 are ported to the new helper function
  - The last commit removes the olf helper which was only used for source compatibility

    fix misspellings
