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 delivery type:
val[63:56] == 3: val[15:8] is flag: val[7:0] is a PPI.
To the flag, bit 0 stands the interrupt mode is edge(1) or level(0) and
bit 1 stands the interrupt polarity is active low(1) or high(0).

Hi,
The below change is spec compliant.
I think you should first test again after the RefOrName stuffs reverted.
Then, if you still can see the issues, the story is:

We are enabling correct initialization order and table parsing facilities.
These patches are part of them.
