Instead of locating the RSDP table below 1MB put it just below 4GB
like the rest of the ACPI tables in case of PVH guests. This will
avoid punching more holes than necessary into the memory map.

Provide ability to load multiple ACPI modules. Thie feature is needed
by PVHv2 guests and will be used in subsequent patches.
We assume that PVHv2 guests do not load their ACPI modules specified
in the configuration file. We can extend support for that in the future
if desired.

... and load BIOS/UEFI firmware into guest memory.
This adds a new firmware module, system_firmware_module. It is loaded in
the guest memory and final location is provided to hvmloader via the
hvm_start_info struct.
This patch create the hvm_start_info struct for HVM guest that have a
device model, so this is now common code with HVM guest without device
model.

This patch use xc_dom_alloc_segment() to allocate the memory space for the
ACPI modules and the SMBIOS modules. This is to replace the arbitrary
placement of 1MB (+ extra for MB alignement) after the hvmloader image.
This patch can help if one add extra ACPI table and hvmloader contain
OVMF (OVMF is a 2MB binary), as in that case the extra ACPI table could
easily be loaded past the address 4MB, but hvmloader use a range of
memory from 4MB to 10MB to perform tests and in the process, clears the
memory, before loading the modules.

Error path in xc_dom_load_hvm_kernel needs to use the 'error' label instead
of directly returning. This is needed so the entries local variable is
freed.
