ASoC: max98090/91: adding two virtual Mux widgets for digital mics

The two digital mics M1(primary digital mic) and M2(secondary digital
mic) work independently of one another. It means they could be switched
On or Off independently of one another. To control their On or Off
state, with this patch creating two virtual multiplexer widgets
"DMIC M1 Mux" and "DMIC M2 Mux", with two options "Enable" and "Disable".
