ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()
acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use guid_t type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. Acked-by: Rafael J.
