[PATCH 1/1] platform/x86: pmc_atom: Add several Beckhoff Automation boards to critclk_systems DMI table

[linux-kernel-dev]

From: Steffen Dirkwinkel <s.dirkwinkel@xxxxxxxxxxxx>

There are several Beckhoff Automation industrial PC boards which use
pmc_plt_clk* clocks for ethernet controllers. This adds affected boards
to critclk_systems DMI table so the clocks are marked as CLK_CRITICAL and
not turned off.

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