[PATCH v5 1/4] PCI: Add 32 GT/s decoding in some macros

[Bjorn Helgaas <helgaas@kernel.org>]

From: Yicong Yang <yangyicong@hisilicon.com>

Link speed 32.0 GT/s is supported in PCIe r5.0. Add this speed to
PCIE_SPEED2STR() and PCIE_SPEED2MBS_ENC() to correctly decode it.

This is complementary to de76cda215d5 ("PCI: Decode PCIe 32 GT/s link
speed").
