boot/platform/efi: Add network booting support

Similar to open firmware implementation. This allows to load the kernel from a remote_disk_server. IP address is recovered using LoadOptions with a syntax similar to the Linux kernel network boot "ip" parameter. If this is not set, no network booting is attempted, in order to not slow down normal booting by waiting on network traffic.
