The 5784 B step and newer chips require the PHY DSPs to be fine-tuned
based on one-time programmable values stored in the chip.  This is
essential to achieve optimal PHY operations especially when using
long cables.  We also need to properly handle the 10Mbit RX bit in the
CPMU_CTRL register during PHY reset.

Update version to 3.89.
