rG59219fc76a4b: loader.efi: efiblk_memdisk_preload passes the VirtualDisks to FreeBSD

Summary

Set hint.md.%d.physaddr and hint.md.%d.len for each of the VirtualDisks.
The memory for these remains after we exit boot services so FreeBSD can
use them. This leverages the BIOS work we did for memdisks. In
hindsight, I should have passed this in via metadata, but it's been in a
release.
