Add PCIe scan option to BMC Feature Control command

This adds an option to enable and disable the PCIe scan feature using
the MTM BMC Feature Control command.

Changes to request bytes for PCIe scan feature:
Byte 1 – Supported features
    01h - PCIe scan
Byte 2 – Enable/Disable feature
    00h – Stops the given feature
    01h – Starts the given feature
    02h – Disables the given feature
    03h – Enables the given feature
Byte 3:5 – reserved

Tested:
Verified PCIe scan feature can be enabled/disabled as expected in MTM mode

Disable PCIe scan:
ipmitool raw 0x30 0xa4 1 2 0 0 0

Enable PCIe scan:
ipmitool raw 0x30 0xa4 1 3 0 0 0
