On this board, BCLK and LRCLK are wired the other way around: SAI2 must be bus master, with the codec as I2S slave. Move dailink_master to the CPU sub-node so SAI2 drives BCLK and LRCLK, fixing broken audio on the PHYTEC phyBOARD-Pollux-i.MX8MP board with PEB-AV-10 Audio/Video expansion board. Also remove the spurious clocks property from the codec sub-node, which had no effect in this topology.
