ACPICA: Utilities: Cleanup to remove useless ACPI_PRINTF/FORMAT_xxx helpers.
commit 1d0a0b2f6df2bf2643fadc990eb143361eca6ada upstream. ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6 For physical addresses, since the address may exceed 32-bit address range after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT and ACPI_FORMAT_UINT64() instead of ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT(). This patch also removes above replaced macros as there are no users. This is a preparation to switch acpi_physical_address to 64-bit on 32-bit kernel builds.
