Add support for the PWM controller found in Amlogic Meson SoCs.
This controller provides a dual PWM output with 4 selectable clock source
and a two level divider to achieve a better PWM range.

Currently Meson8b and GXBB SoCs are supported.

Changes since v2 at http://lkml.kernel.org/r/1471718083-11516-1-git-send-email-narmstrong at baylibre.com :
- Switch to apply() callback only, this fixes the setup sequence
- Implement get_state
- Make clock parent names as DT match data

Changes since v1 at http://lkml.kernel.org/r/1466173784-15625-1-git-send-email-narmstrong at baylibre.com :
- fix meson8b dtsi
