platform/x86: pmc_atom: Add Lex 3I380D industrial PC to critclk_systems DMI table
[ Upstream commit 3d0818f5eba80fbe4c0addbfe6ddb2d19dc82cd4 ] The Lex 3I380D industrial PC has 4 ethernet controllers on board which need pmc_plt_clk0 - 3 to function, add it to the critclk_systems DMI table, so that drivers/clk/x86/clk-pmc-atom.c will mark the clocks as CLK_CRITICAL and they will not get turned off. Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL") Reported-and-tested-by: Semyon Verchenko <semverchenko@factor-ts.ru> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
