In v3.0 the msrfield class has its initializer changed in a way that is
incompatible with the parameter names or the getter/setter. When introduced
from the BITS project, that class allows specifying an MSR field of
arbitrary length by being given the index of the most and least significant
bits.
This patch restores the original behavior of that msrfield class and moves
the use-case specific methods, namely is_vmx_cap_supported and
is_ctrl_setting_allowed, to a helper class.
Parsing of the VMX capability reporting MSRs in msr.py are updated
accordingly, and brief documentation of the MSR fields are added as well.

1. check if VMX feature is enabled in the BIOS setting.
If disabled, board inspector will show error message.
2. check if Hyper-Threading is enabled in the BIOS setting.
If enabled, board inspector will show warning message.
3. check if VT-d is enabled in the BIOS setting.
If disabled, board inspector will show error message.
v2-->v3:
Use the class names instead of addresses, and invoke the rdmsr method
of each class.
v1-->v2:
1. For the Hyper-Threading BIOS check, update the log level to the warning.
2. For VMX invalid BIOS check, the XDS does the actual check,
the board inspector only collects information.

Add CPU capability checks.
If a feature is not supported on this processor, the board inspector
will show error message because it would impact ACRN’s ability
to function properly.
v3-->v4:
Update the error messages.
v2-->v3:
1. For VMX features, split each feature as a separate property, capability
checks in XML schema will then check all those features.
2. Use the class names instead of addresses, and invoke the rdmsr method
of each class.
v1-->v2:
1. Define each register as a class inheriting the `MSR` class defined
in platformbase.py, and define each bit as fields of that class.
2. The board inspector simply collects the CPU capability and attribute,
and the XSD does the actual check

This patch adds schema-based board checks mechanism.
This provides integrators with a mechanism that XSD does
the actual board data check.
