liujunming 538e7cf74d hv:cpu-caps:refine processor family and model info
v3 -> v4:
Refine commit message and code stype

1.
SDM Vol. 2A 3-211 states DisplayFamily = Extended_Family_ID + Family_ID
when Family_ID == 0FH.
So it should be family += ((eax >> 20U) & 0xffU) when Family_ID == 0FH.

2.
IF (Family_ID = 06H or Family_ID = 0FH)
	THEN DisplayModel = (Extended_Model_ID « 4) + Model_ID;
While previous code this logic:
IF (DisplayFamily = 06H or DisplayFamily = 0FH)

Fix the bug about calculation of display family and
display model according to SDM definition.

3. use variable name to distinguish Family ID/Display Family/Model ID/Display Model,
then the code is more clear to avoid some mistake

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
