arm: mvebu: a38x: Adjust UTMI PHY parameters
When running USB compliance tests on our Armada-385 hardware platforms
we have seen some eye mask violations. Marvell's internal documentation
says: Based on silicon test results, it is recommended to change the
impedance calibration threshold setting to 0x6 prior to calibration.
Port changes from Marvell's u-boot fork[1] to address this.
