[PATCH v1] riscv: dts: icicle: Add GPIO controlled LEDs

[Emil Renner Berthing <emil.renner.berthing@canonical.com>]

This adds the 4 GPIO controlled LEDs to the Microchip PolarFire-SoC
Icicle Kit device tree. The schematic doesn't specify any special
function for the LEDs, so they're added here without any default
triggers and named led1, led2, led3 and led4 just like in the schematic.
