Turned out that PLL_P_OUT4 is the parent of CDEV2 clock and original clock setup of "ulpi-link" was correct. The reverted patch was fixing USB for one board and broke the other, now Tegra's clk driver correctly sets parent for the CDEV2 clock and hence patch could be reverted safely, restoring USB for all of the boards.
