Back when audio was enabled, the muxing of some MPP pins was causing problems. However, since commit fea038ed55ae ("ARM: mvebu: Add proper pin muxing on the Armada 370 DB board"), those problematic MPP pins have been assigned a proper muxing for the Ethernet interfaces. This proper muxing is now conflicting with the hog pins muxing that had been added as part of 249f3822509b ("ARM: mvebu: add audio support to Armada 370 DB").
Therefore, this commit simply removes the hog pins muxing, which solves a warning a boot time due to the conflicting muxing requirements.
