ARM: dts: msm: Fix MCLK routing for MAD for msm8994

The AIF4 MAD widget can be used by use cases that are not routed to MCLK
and hence resulting in enabling the MCLK when it is not needed by the
use case. Update the routing for all msm8994 platforms so that MCLK can
be enabled only for needed endpoints.
