Do we also need new cases in pcie_get_speed_cap and PCIE_SPEED2MBS_ENC?

Indeed, I missed that.

Add support for the new speeds in pcie_get_speed_cap() and PCIE_SPEED2MBS_ENC().

While here, fix the values of the PCI_EXP_LNKCAP_SLS_*. They are supposed to increase sequentially. They are not bitfields. This will be committed separately.
