In the hypervisor, VMCS fields include 16-bit fields,
32-bit fields, 64-bit fields and natural-width fields.
In the current implement, no exec_vmread32/exec_vmwrite32
is for accessing 32-bit fields. So there are many type
casting for the return value and parameters vmread/vmwrite
operations.
Create exec_vmread32 and exec_vmwrite32 functions to
access 32-bit fields in VMCS;
Update related variables type for vmread/vmwrite operations;
Update related caller according to VMCS fields size.
V1--V2:
This is new part of this patch serial to only
update 32 bit vmread/vmread opertions and related
caller.
V2-->V3:
Update related variables type in data structure
for exec_vmread32/exec_vmwrite32.
Rename temp variable 'low' into 'value' for
exec_vmread32;
V3-->V4:
Remove useless type conversion.
