PCI: qcom: Use PCIE_SPEED2MBS_ENC() macro for encoding link speed

Browse source

Instead of hardcoding the link speed in MBps, use existing
PCIE_SPEED2MBS_ENC() macro that does the encoding of the link speed for
us. Also, let's Wrap it with QCOM_PCIE_LINK_SPEED_TO_BW() macro to do
the conversion to ICC speed.

This eliminates the need for a switch case in qcom_pcie_icc_update() and
also works for future Gen speeds without any code modifications.
