[PATCH 2/3] pwm: meson: add clock source configuratin for Meson-AXG

[Yixun Lan <yixun.lan@amlogic.com>]

From: Jian Hu <jian.hu@amlogic.com>

For PWM controller in the Meson-AXG SoC, the EE domain and
AO domain have different clock source. This patch try to describe
them in the DT compatible data.
