qcacld-3.0: Add new Ini to control pcie gen and lane params

As per the requirement, add a new Ini CFG_PCIE_CONFIG to
enable or disable externally. This Ini is used to control
pcie generation speed and lane width parameters to max value.
If enabled as of now this Ini makes generation as 3 and lanes
as 2 for pcie.
