[PATCH 1/2] PCI: tegra: Remove support for ZRX-DC compliant PHY from platform driver

[Anvesh Salveru]

As part of dw_pcie_setup(), PHYs which are compliant to ZRX-DC
specification are already handled based on "snps,phy-zrxdc-compliant"
property in controller DT node. So, instead of handling ZRX-DC
compliant settings in each platform driver, remove this driver
specific code.
