x86: mmio: Skip over address size prefix found in x32 code
The prefix does appear in guests compiled with "-mx32". In the
instruction parser we just have to skip over it.
The patch also adds a few of these instructions to the mmio testcase.

x86: Fix long mode detection
If the guest is currently running in long mode does not only depend on
EFER having it enabled. We also need to check if CS.L is set. If L is 0,
we are actually in compatibility mode.
Rework vcpu_vendor_get_cs() to vcpu_vendor_get_cs_attr() so that it
returns all needed information about the CS segment. This includes L,
the DPL for the current privilege level and already the D/B bit which
will be needed soon by the instruction parser.

x86: mmio: Fix address width calculation
As we are claiming to support the affected instructions, we should get
this completely right: When not in long mode, the combination of the
address-size prefix and the D/B bit from CS defines if we are using 16
or 32 bit addresses.
A similar pattern may eventually be useful to support the operand-size
prefix for with 16-bit accesses.

configs: arm: add comm_region to all inmates
comm_region will become mandatory for all of our inmates.
On x86, we already use the communication region to pass certain platform
specific information to guests. So let's do this on all ARM
architectures as well. This patch is a preparation for that.
Let's use guest paddr 0x80000000 (2GiB) for the comm region, which
doesn't seem to collide with any existing (MMIO) region of our current
inmates.

arm64: restructure get_cpu_parange
On ARM64 Big/Little Platform, such as i.MX8QM,
there are two types of Cortex-A CPUs, Cortex-A53 and Cortex-A72.
A53 ID_AA64MMFR0_EL1 shows its physical address range supported is 40bits.
A72 ID_AA64MMFR0_EL1 shows its physical address range supported is 44bits.
The minimal value 40 needs to be used as cpu parange, if using 44,
A53 will be broken. So need to iterate the cpu parange of all the
CPUs to find out the smallest one.
Add a new percpu entry id_aa64mmfr0 whose low 4 bits holds parange.
Fill id_aa64mmfr0 before runs into entry
Move arm64 get_cpu_parange out to a new file
Use percpu id_aa64mmfr0 in get_cpu_parange and choose the smallest value
Then each time using get_cpu_parange, the smallest one will
be chosen.
