Code Issues

x86: add missing Lex 3I380NX network detection

Browse Source 
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 all Lex Baytrail devices.

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.
