phy: tegra: xusb: Increase timeout for USB2_TRK_COMPLETED polling
On Tegra264, the UTMI bias tracking circuit runs at 1 MHz and needs
more cycles for the biases to settle than on earlier SoCs such as
Tegra234. The existing timeout is therefore not long enough and can
cause spurious polling failures during bias pad power-on. Therefore,
increase the timeout to 200 cycles to support Tegra264 devices
