[PATCH 4.14 34/53] platform/x86: pmc_atom: Add several Beckhoff Automation boards to critclk_systems DMI table

[Greg Kroah-Hartman]

[ Upstream commit d6423bd03031c020121da26c41a26bd5cc6d0da3 ]

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")
