[PATCH v3 2/2] x86: fix build warning int-to-pointer-cast

[Vamshi K Sthambamkadi]

Fix warning on x86_32:
arch/x86/boot/compressed/acpi.c:316:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

This is because on 32 bit, cast of acpi_physical_address(u64) to rsdp
pointer in get_acpi_srat_table() triggers this warning.
