Add 32 GT/s decoding in some macros as a complementary 2. Remove redundancy in speed presentation process and improve the codes. Currently We use switch-case statements to acquire the speed string according to the pci bus speed in current_link_speed_show() and pcie_get_speed_cap(). It leads to redundant and when new standard comes, we have to add cases in the related functions, which is easy to omit at somewhere. Abstract the judge statements out. Use macros and pci speed arrays instead. Then only the macros and arrays need to be extended when next generation comes.

And modify the description as suggested. 2. split "PCI: Refactor bus_speed_read() with PCI_SPEED2STR macro" to two patches.
