phy: tegra: xusb: Disable periodic tracking on Tegra234
commit 7be54870e9bf5ed0b4fe2a23b41a630527882de5 upstream.
Periodic calibration updates (~10µs) may overlap with transfers when
PCIe NVMe SSD, LPDDR, and USB2 devices operate simultaneously, causing
crosstalk on Tegra234 devices. Hence disable periodic calibration updates
and make this a one-time calibration.
