platform/x86: pmc_atom: Add Siemens CONNECT X300 to critclk_systems DMI table

commit e8796c6c69d129420ee94a1906b18d86b84644d4 upstream.

The CONNECT X300 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.
Tested on CONNECT X300.
