intel_idle: Add CPU model 54 (Atom N2000 series)
Add CPU ID for Atom N2600/N2800 processors. Datasheets indicate support for this, detailed information about potential quirks or limitations are missing, though. So we just reuse the definition for the previous ATOM series. Tests on N2800 systems showed that this addition is fine an can reduce power consumption by about 0.25 W (personally confirmed on Intel DN2800MT).
