This is carrying the fix from below commit for rt5672 machine driver

commit 583e58a0f0e996008780fe4df0f7640890a9b69a

    ASoC: Intel: Remove ignore suspend support

    In our platform we want platform and codec driver routines to get
invoked
    and don't need the machine routines so remove here

that also can be done.

the expected name is i2c-10EC5650:00 i could reduce the array size
