Haotien Hsu 248ba00d13 phy: tegra: xusb: Disable periodic tracking on Tegra234 
commit 7be54870e9 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.
