[U-Boot] [PATCH 3/4] sunxi: display: Also use the PWM controller for backlight on sun7i

[Paul Kocialkowski]

Using PWM to drive the backlight pin instead of a GPIO provides various
advantages, that are described in commit 421c98d7d2 ("sunxi: display:
Use PWM to drive backlight where applicable").

Defining SUNXI_PWM_PIN0 triggers the configuration of the PWM controller
in the display driver.
