RISC-V: Add BeagleV Starlight Beta device tree
Add initial device tree for the BeagleV Starlight Beta board. About 300 of these boards were sent out as part of a now cancelled BeagleBoard.org project. I2C timing data is based on the device tree in the vendor u-boot port. Heartbeat LED added by Geert.
