platform/x86: pmc_atom: Match all Lex BayTrail boards with critclk_systems DMI table

[ Upstream commit c9d959fc32a5f9312282817052d8986614f2dc08 ]

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.

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