backlight: aw99706: Fix build errors caused by wrong gpio header

Browse Source 
The driver uses GPIO descriptor API (devm_gpiod_get,
gpiod_set_value_cansleep, GPIOD_OUT_LOW) but includes the legacy
<linux/gpio.h> header instead of <linux/gpio/consumer.h>.

When CONFIG_GPIOLIB is not set, <linux/gpio.h> does not include
<linux/gpio/consumer.h>, causing build errors:

  error: implicit declaration of function 'gpiod_set_value_cansleep'
  error: implicit declaration of function 'devm_gpiod_get'
  error: 'GPIOD_OUT_LOW' undeclared

Fix by including the correct header <linux/gpio/consumer.h>.
