It's widely used in older i.MXs according to their DTS files. So
it should be safer to just leave SSI over here.

And I actually doubt the feasibility of running this driver with
i.MX6UL as there might not be an AUDMUX on i.MX6UL since it does
not have SSI any more while the driver always touches the address
space of AUDMUX which may not exist on i.MX6UL.
