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.

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

Relocate ACPI address to 0x7fe00000 and ACPI NVS to 0x7ff00000 correspondingly.
In this case, we could include TPM event log region [0x7ffb0000, 0x80000000)
into ACPI NVS.

When guest doing BAR re-programming, we should check whether
the base address of the BAR is valid.This patch does this check by:
1. whether the gpa is located in the responding MMIO window
2. whether the gpa is aligned with the BAR size

On WHL platform, we need to pass through TPM to Secure pre-launched VM. In order
to do this, we need to add TPM2 ACPI Table and add TPM DSDT ACPI table to include
the _CRS.
Now we only support the TPM 2.0 device (TPM 1.2 device is not support). Besides,
the TPM must use Start Method 7 (Uses the Command Response Buffer Interface)
to notify the TPM 2.0 device that a command is available for processing.

Add FADT table support to support guest S5 setting.
According to ACPI 6.3 Spec, OSPM must ignored the DSDT and FACS fields if them're zero.
However, Linux kernel seems not to abide by the protocol, it will check DSDT still.
So add an empty DSDT to meet it.
