phy: tegra: p2u: Set ENABLE_L2_EXIT_RATE_CHANGE in calibration
Set ENABLE_L2_EXIT_RATE_CHANGE register bit to request UPHY PLL rate change
to Gen1 during initialization. This helps in the below surprise link down
cases,
- Surprise link down happens at Gen3/Gen4 link speed.
- Surprise link down happens and external REFCLK is cut off, which causes
UPHY PLL rate to deviate to an invalid rate.
