x86: add missing Lex 3I380NX network detection
The Lex 3I380NX 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.
This commit is nearly redundant to 3d0818f5eba8 ("platform/x86:
pmc_atom: Add Lex 3I380D industrial PC to critclk_systems DMI table")
but for the 3I380NX device.
The original vendor firmware is only available using the WaybackMachine:
