Add emulation code to emulate read/write access to pl011 registers

As we have generic functions to get device list
(libxl__device_list) no need to have callback in
the framework. To resolve issue when XS entry
doesn't match device name, device type is
extended with field "entry" which keeps XS entry.

We have generic functiont to get/free device list:
libxl__device_list and libxl__device_list_free
As some devices have different from their name entry
in XS (disk -> vbd), getting list function
takes XS entry as paramater. This doesn't allow
to call libxl__device_list fr
Currently Linux has no support for grant v2 as this would reduce the
maximum number of active grants by a factor of 2 compared to v1,
because the number of possible grants are limited by the allowed number
of grant frames and grant entries of v2 need twice as much bytes as
those of v1.
Unfortunate
Delay the allocation of the grant table sub structures in order to
allow modifying parameters needed for sizing of these structures at a
per domain basis. Allocate the structures and the table frames only
from grant_table_set_limits() (dom0: from grant_table_create()).

When creating a Xenstore stubdom set the grant limits: the stubdom
will need to setup a very limited amount of grants only, so 4 grant
frames are enough. For being able to support up to 32768 domains it
will need 128 maptrack frames (1 mapping per domain, 256 maptrack
entries per maptrack frame).
Add xl.conf config items for default values of grant limits:
max_grant_frames will set the default for the maximum number of grant
frames for a domain which will take effect if the domain's config file
doesn't specify a value. If max_grant_frames isn't set in xl.conf it
will default to 32 for host
Add new domain config items for setting the limits for the maximum
numbers of grant table frames and maptrack frames of a domain.

V4:
- rename configuration it
Instead of using the same global resource limits of grant tables (max.
number of grant frames, max. number of maptrack frames) for all domains
make these limits per domain. Set those per-domain limits in
grant_table_set_limits(). The global settings are serving as an upper
boundary now which must n
Add the maximum possible mfn of the host to the libxl_physinfo

Add a function for obtaining the highest possible physical memory
address of the system. This value is influenced by:
- hypervisor configuration (CONFIG_BIGMEM)
- processor capability (max. addressable physical memory)
- memory map at boot time
- memory hotplug capability
Add this value to xen_sy
Instead of attaching the ARM specific grant table data to the domain
structure add it to struct grant_table. Add the needed arch functions
to the asm-*/grant_table.h includes.

- correct and clea
On very large hosts a pv-guest needs to know whether it will have to
handle frame numbers larger than 32 bits in order to select the
appropriate grant interface version.
Add a new Xen specific CPUID node to contain the maximum machine address
width similar to the x86 CPUID node 0x8008 containi
Add a new libxc function xc_domain_set_gnttbl_limits() setting the
limits for the maximum numbers of grant table frames and maptrack
frames of a domain.
