hw/i386/xen/: move xen-mapcache.c to hw/xen/
xen-mapcache.c contains common functions which can be used for enabling Xen on
aarch64 with IOREQ handling. Moving it out from hw/i386/xen to hw/xen to make it
accessible for both aarch64 and x86.

hw/i386/xen: rearrange xen_hvm_init_pc
In preparation to moving most of xen-hvm code to an arch-neutral location,
move non IOREQ references to:
- xen_get_vmport_regs_pfn
- xen_suspend_notifier
- xen_wakeup_notifier
- xen_ram_init
towards the end of the xen_hvm_init_pc() function.
This is done to keep the common ioreq functions in one place which will be
moved to new function in next patch in order to make it common to both x86 and
aarch64 machines.

In preparation to moving most of xen-hvm code to an arch-neutral location, move:
- shared_vmport_page
- log_for_dirtybit
- dirty_bitmap
- suspend
- wakeup
out of XenIOState struct as these are only used on x86, especially the ones

Updated XenIOState can be used for both aarch64 and x86.
Also, remove free_phys_offset as it was unused.

xen-hvm: reorganize xen-hvm and move common function to xen-hvm-common
This patch does following:
1. creates arch_handle_ioreq() and arch_xen_set_memory(). This is done in
preparation for moving most of xen-hvm code to an arch-neutral location,
move the x86-specific portion of xen_set_memory to arch_xen_set_memory.
Also, move handle_vmport_ioreq to arch_handle_ioreq.
2. Pure code movement: move common functions to hw/xen/xen-hvm-common.c
Extract common functionalities from hw/i386/xen/xen-hvm.c and move them to
hw/xen/xen-hvm-common.c. These common functions are useful for creating
an IOREQ server.
xen_hvm_init_pc() contains the architecture independent code for creating
and mapping a IOREQ server, connecting memory and IO listeners, initializing
a xen bus and registering backends. Moved this common xen code to a new
function xen_register_ioreq() which can be used by both x86 and ARM
machines.
Following functions are moved to hw/xen/xen-hvm-common.c:
xen_vcpu_eport(), xen_vcpu_ioreq(), xen_ram_alloc(), xen_set_memory(),
xen_region_add(), xen_region_del(), xen_io_add(), xen_io_del(),
xen_device_realize(), xen_device_unrealize(),
cpu_get_ioreq_from_shared_memory(), cpu_get_ioreq(), do_inp(),
do_outp(), rw_phys_req_item(), read_phys_req_item(),
write_phys_req_item(), cpu_ioreq_pio(), cpu_ioreq_move(),
cpu_ioreq_config(), handle_ioreq(), handle_buffered_iopage(),
handle_buffered_io(), cpu_handle_ioreq(), xen_main_loop_prepare(),
xen_hvm_change_state_handler(), xen_exit_notifier(),
xen_map_ioreq_server(), destroy_hvm_domain() and
xen_shutdown_fatal_error()
3. Removed static type from below functions:
1. xen_region_add()
2. xen_region_del()
3. xen_io_add()
4. xen_io_del()
5. xen_device_realize()
6. xen_device_unrealize()
7. xen_hvm_change_state_handler()
8. cpu_ioreq_pio()
9. xen_exit_notifier()
4. Replace TARGET_PAGE_SIZE with XC_PAGE_SIZE to match the page side with Xen.

This is done to prepare for enabling xenpv support for ARM architecture.
On ARM it is possible to have a functioning xenpv machine with only the
PV backends and no IOREQ server. If the IOREQ server creation fails,
continue to the PV backends initialization.

hw/arm: introduce xenpvh machine
Add a new machine xenpvh which creates a IOREQ server to register/connect with
Xen Hypervisor.
Optional: When CONFIG_TPM is enabled, it also creates a tpm-tis-device, adds a
TPM emulator and connects to swtpm running on host machine via chardev socket
and support TPM functionalities for a guest domain.
Extra command line for aarch64 xenpvh QEMU to connect to swtpm:
-chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-machine tpm-base-addr=0x0c000000 \
swtpm implements a TPM software emulator(TPM 1.2 & TPM 2) built on libtpms and
provides access to TPM functionality over socket, chardev and CUSE interface.
Github repo: https://github.com/stefanberger/swtpm
Example for starting swtpm on host machine:
mkdir /tmp/vtpm2
swtpm socket --tpmstate dir=/tmp/vtpm2 \
--ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock &
