Move xen_early_init() before efi_init(), then when calling efi_init()
could initialize Xen specific UEFI.
Check if it runs on Xen hypervisor through the flat dts.

Add a new function to parse DT parameters for Xen specific UEFI just
like the way for normal UEFI. Then it could reuse the existing codes.
If Xen supports EFI, initialize runtime services.
