acpi_table: Fix coverity defect in acpi_write_spcr

Fix "Integer handling issues  (SIGN_EXTENSION)" in newly added code:
Cast serial_info.reg_offset to u64 to prevent an integer overflow when
shifted too many bits to the left. Currently this never happens as the
shift is supposed to be less than 4.
