OpenBSD Adds Raspberry Pi 5 Support, but with Known Issues

A recent OpenBSD update adds support for RAMDISK on the Raspberry Pi 5 Model B. However, there are known issues: booting from PCIe storage HATs doesn't work (due to missing U-Boot support), WiFi on the Raspberry Pi 5 Model B "d0" boards is broken, and the active cooler (fan) doesn't function due to missing pwm/clock drivers (work in progress).
