HV: Fix the problems in ve820 acpi area

Browse Source 
The length of the ACPI data entry in ve820 tab was 960K, while the
ACPI file is 1MB. It causes the ACPI file copy failed due to reserved
ACPI regions in ve820 table is not enough when loading pre-launched
VMs. This patch changes ACPI data area to 1MB to fix the problem.

And the ACPI data length was missed when calculating
ENTRY_HPA1_LOW_PART2 length. Fixed here too.

Also adds some refinement to the hard-coded ACPI base/addr definations

Tracked-On: #6674
