Move GuestAddress and GuestMemory to a new crate for VM memory. This
will make separating sys_util and crosvm independent making it easier
to use sys_util functions outside of crosvm.

Add the AML support to generate the S1 table instead of hard coding.
Also use the IO allocater to allocate the IO resouce for ACPI PM.
BUG=None
TEST=boot crosvm by command "crosvm run -s crosvm.sock -m 4096 --cpus 4
--rwdisk rootfs.img -p "root=/dev/vda rootfstype=ext4" vmlinux".
Check the S1 capability by "#echo standby > /sys/power/state" from guest
side. Linux guest is suspended. And resume linux guest by "#crosvm resume
crosvm.sock" from host side.

S1 is a sleep state which is lighter than S3, but enough to put the devices
into the suspended state.
With this DSDT, the guest kernel is able to see the S1 capability and to
put the VM into virtual S1. During the virtual S1, guest kernel will call
each suspend callbacks of the devices driver to put the devices into the
suspend state, including the pass through device.

Add acpi_rsdp_addr in boot_params to allow crosvm to pass
a physicall address of RSDP to the Linux guest kernel, so
that the linux guest kernel can parse the constructed ACPI
tables and enable the ACPI.
Although there is ACPI tables but as we still have "acpi=off"
in command line parameter, there is still no ACPI in guest kernel.
The ACPI construction refers to the implementation of the
