[PATCH v4 4/4] pwm: meson: Add support for Amlogic S7

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao at amlogic.com>

Add support for Amlogic S7 PWM. Amlogic S7 different from the previous
SoCs, a controller includes one pwm, at the same time,the controller has
only one input clock source.

Also use the kernel coding style for the empty of_device_id terminator.
