    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:

+Subject: platform/x86: pmc_atom: Match all Lex BayTrail boards with
+ critclk_systems DMI table
+
+The critclk_systems[] DMI match table already contains 2 Lex BayTrail
+boards and patches were just submitted to add 3 more entries for the
+following models: 3I380NX, 3I380A, 3I380CW.
+
+Looking at: https://www.lex.com.tw/products/embedded-ipc-board/
+we can see that Lex BayTrail makes many embedded boards with
+multiple ethernet boards and none of their products are battery
+powered so we don't need to worry (too much) about power consumption
+when suspended.
+
+Add a new DMI match which simply matches all Lex BayTrail boards and drop
+the 2 existing board specific quirks.
