HV: add Kconfig of CONSTANT_ACPI

Browse Source 
If CONFIG_CONSTANT_ACPI is true, then the value in host_acpi_info structure
is constant. Otherwise the host_acpi_info value could be overrided.

This is useful when platform ACPI table value is not fixed in Bootloader
before production.

In production release, this config should be set to yes.

Tracked-On: #1264
