Subject: [PATCH] platform/x86: pmc_atom: Add Siemens CONNECT X300 to critclk_systems DMI table

Git-commit: e8796c6c69d129420ee94a1906b18d86b84644d4

Patch-mainline: v5.5-rc3

References: bsc#1051510

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.

Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
