ACPI: use device name LNXSYBUS.xx for ACPI \_SB and \_TZ objects

Use device name "LNXSYBUS:xx" instead  of "device.xx" for ACPI objects
\_SB and \_TZ.

BTW, the original check of "handle == ACPI_ROOT_OBJECT" in statment
"else if (list_empty(&pnp->ids) && handle == ACPI_ROOT_OBJECT)"
is always false because of the code at the begin of that block.
                if (handle == ACPI_ROOT_OBJECT) {
                        acpi_add_id(pnp, ACPI_SYSTEM_HID);
                        break;
                }
