HV: move the ve820 GPU OpRegion address

Browse Source 
The ve820 table' hpa1_low area is divided into two parts, which
is making the code too complicated and causing problems. Moving
the entries that divides the hpa1_low could make things easier.

This patch moves the GPU OpRegion to the tail area of 2G,
consecutive to the acpi data/nvs area.

before:
|<---low_1M--->|
|<---hpa1_low_part1--->|
|<---SSRAM--->|
|<---GPU_OpRegion--->|
|<---hpa1_low_part2--->|
|<---ACPI DATA--->|
|<---ACPI NVS--->|
---2G---

after:
|<---low_1M--->|
|<---hpa1_low_part1--->|
|<---SSRAM--->|
|<---hpa1_low_part2--->|
|<---GPU_OpRegion--->|
|<---ACPI DATA--->|
|<---ACPI NVS--->|
---2G---
