UefiPayloadPkg: Align base address for ACPI region 

In platform which support ACPI 2.0 only, the base address of ACPI region
is not page aligned. This unalinged base address leads to failure at
BuildMemoryAllocationHob when parsing ACPI node in FdtParserLib, before
building gUniversalPayloadAcpiTableGuid GUID HOB.

Align base address of ACPI region down to EFI_PAGE_SIZE to make sure
base address always aligned.
