Subject: [PATCH 4.14 138/148] platform/x86: pmc_atom: Add Lex 2I385SW to critclk_systems DMI table

From: Georg Müller <georgmueller@....net>

commit 95b31e35239e5e1689e3d965d692a313c71bd8ab upstream.

The Lex 2I385SW board has two Intel I211 ethernet controllers. Without
this patch, only the first port is usable. The second port fails to
start with the following message:

    igb: probe of 0000:02:00.0 failed with error -2

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