pvh: use x86/HVM direct boot ABI
These changes (along with corresponding QEMU and Linux kernel changes)
enable a guest to be booted using the x86/HVM direct boot ABI.
QEMU parses the uncompressed kernel binary passed to it via -kernel
to read the ELF Note which contains the address to be loaded. QEMU
then depends on qboot to populate the start_info struct needed by
the direct boot ABI and configure the guest e820 tables before
jumping to the loaded kernel entry.
