- This PR adds the LED Driver for QEMU RISC-V 32-bit and 64-bit (User LEDs and Auto LEDs) - QEMU RISC-V LED Driver will be used by the Rust Blinky App for Google Summer of Code - Blinking the LED is probably the most common Embedded Demo, and now it's supported by QEMU RISC-V - We added NuttX Configs `rv-virt:leds` and `rv-virt:leds64` to support User LEDs for 32-bit and 64-bit RISC-V - Turning on/off a Simulated User LED will print a log message: "LED 1 set to 1" - The code is derived from NuttX PinePhone LED Driver
