Subject: [PATCH 039/250] arm64: Add "--nounzip" option support in xen_module
 command

This patch adds "--nounzip" option support in order to
be compatible with the module command of multiboot on other architecture,
by this way we can simplify grub-mkconfig support code.

This patch also allow us to use zip compressed module(like Linux kernel
for Dom0).
