platform/x86: pmc_atom: Add Siemens SIMATIC IPC227E to critclk_systems DMI table
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. Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL") Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
