platform/x86: pmc_atom: Add Siemens SIMATIC IPC227E to critclk_systems DMI table



commit ad0d315b4d4e7138f43acf03308192ec00e9614d upstream.

The SIMATIC IPC227E uses the PMC clock for on-board components and gets
stuck during boot if the clock is disabled. Therefore, add this device
to the critical systems list.
