tests: common: skip arch_nop testing on some physical x86 board

Browse source 
Using the NOP instructions to do timing control on some physical board
such as ehl_crb, up_squared and intel adsp board, that doesn't work.
It seems like it can only be used for instruction alignment purposes.
We skip this test on this board because it's not meaningful.

Fixes #35971
