DellEMC S6100 disable pericom/xlinx chipset

[paavaanan]

- Why I did it

• Xilinx/pericom peripherals are not actively used in DellEMC S6100 switch.
• These peripherals are throwing PCIE corrected messages in some of the units and filling syslog.
• Since it is not usable disabling it at startup.

- How I did it

• Removing from PCIE sub-system

- How to verify it
