pvh: Boot uncompressed kernel using direct boot ABI
These changes (along with corresponding Linux kernel and qboot changes)
enable a guest to be booted using the x86/HVM direct boot ABI.
This commit adds a load_elfboot() routine to pass the size and
location of the kernel entry point to qboot (which will fill in
the start_info struct information needed to to boot the guest).
Having loaded the ELF binary, load_linux() will run qboot
which continues the boot.
The address for the kernel entry point is read from an ELF Note
in the uncompressed kernel binary by a helper routine passed
to load_elf().
