arm: mvebu: a38x: serdes: Don't set PCIe Common Clock Configuration
Enabling Common Clock Configuration bit in PCIe Root Port Link Control Register should not be done unconditionally. It is enabled by operating system as part of ASPM. Also after enabling Common Clock Configuration it is required to do more work, like retraining link. Some cards may be broken due to this incomplete Common Clock Configuration and some cards are broken and do not support ASPM at all. Remove this incomplete code for Common Clock Configuration. It really should not be done in SerDes code as it is not related to SerDes, but to PCIe subsystem.
