[PATCH] riscv: defconfig: enable GPIO LEDs and their triggers

["Frédéric Mahé" <frederic.mahe@cirad.fr>]

Many riscv boards describe gpio-leds in their device tree, 13 of them
with a heartbeat trigger, but defconfig does not enable the LED
subsystem, so these LEDs stay unused.

Enable LEDS_GPIO and the triggers used by in-tree riscv device trees
(heartbeat, disk-activity, default-on), as arm64 defconfig does.

Tested on a Banana Pi BPI-F3: sys-led blinks with the heartbeat trigger.

This patch was prepared with the help of an AI assistant (Claude),
which also ran the build and boot tests.
