Hi,
This series add xenpvh machine for aarch64. Motivation behind creating xenpvh
machine with IOREQ and TPM was to enable each guest on Xen aarch64 to have it's
own unique and emulated TPM.

This series does following:
    1. Moved common xen functionalities from hw/i386/xen to hw/xen/ so those can
       be used for aarch64.
    2. We added a minimal xenpvh arm machine which creates an IOREQ server and
       support TPM.

Also, checkpatch.pl fails for 03/12 and 06/12. These fails are due to
moving old code to new place which was not QEMU code style compatible.
No new add code was added.

Regards,
Vikram

ChangeLog:
    v3->v4:
        Removed the out of series 04/12 patch.

    v2->v3:
        1. Change machine name to xenpvh as per Jurgen's input.
        2. Add docs/system/xenpvh.rst documentation.
        3. Removed GUEST_TPM_BASE and added tpm_base_address as property.
        4. Correct CONFIG_TPM related issues.
        5. Added xen_register_backend() function call to xen_register_ioreq().
        6. Added Oleksandr's suggestion i.e. removed extra interface opening and
           used accel=xen option

    v1 -> v2
    Merged patch 05 and 06.
    04/12: xen-hvm-common.c:
        1. Moved xen_be_init() and xen_be_register_common() from
            xen_register_ioreq() to xen_register_backend().
        2. Changed g_malloc to g_new and perror -> error_setg_errno.
        3. Created a local subroutine function for Xen_IOREQ_register.
        4. Fixed build issues with inclusion of xenstore.h.
        5. Fixed minor errors.
