PCIe clock must not be set in Linux. Done in UBoot.
Because the frequency is not the same if a FPGA is present or not.
FPGA -> 125Mhz
no FPGA -> 100Mhz
By defaut in UBoot frequency is set to 100Mhz and if a bitstream is loaded (periph or all core with «fpga load») the frequency is switched to 125Mhz.
