platform/x86: pmc_atom: Add Siemens SIMATIC IPC277E to critclk_systems DMI table
The SIMATIC IPC277E 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 SIMATIC IPC277E.
Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
