[PATCH 0/1] ARM64: defconfig: add support for PWM LEDs

Some ARM64 boards (such as the Khadas VIM and many other Amlogic based
devices) have one of the LEDs connected through a PWM controller. This
allows dimming the LED.
The ARM64 defconfig does not support the leds-pwm driver yet. Enabling
that also means that we have to enable the default-on LED trigger.
leds-gpio has a (trigger specific) "default-state" property which can
be used to set the default state, while with leds-pwm this has to be
configured using the default-on trigger.
