hv: refine for HPAn setting

Browse Source 
The current code only supports 2 HPA regions per VM.

This patch extended ACRN to support 2+ HPA regions per VM, to use host
memory better if it is scatted among multiple regions.

This patch uses an array to describe the hpa region for the VM, and
change the logic of ve820 to support multiple regions.

This patch dependent on the config tool and GPA SSRAM change
