phy: tegra: xusb: Disable periodic tracking on Tegra234

JIRA: https://issues.redhat.com/browse/RHEL-116016

  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.
