Pali Rohár 1bba735ddf powerpc/fsl-pci: Fix Class Code of PCIe Root Port 
commit 0c551abfa004ce154d487d91777bf221c808a64f upstream.

By default old pre-3.0 Freescale PCIe controllers reports invalid PCI Class
Code 0x0b20 for PCIe Root Port. It can be seen by lspci -b output on P2020
board which has this pre-3.0 controller:

  $ lspci -bvnn
  00:00.0 Power PC [0b20]: Freescale Semiconductor Inc P2020E [1957:0070] (rev 21)
          !!! Invalid class 0b20 for header type 01
          Capabilities: [4c] Express Root Port (Slot-), MSI 00

Fix this issue by programming correct PCI Class Code 0x0604 for PCIe Root
Port to the Freescale specific PCIe register 0x474.

With this change lspci -b output is:

  $ lspci -bvnn
  00:00.0 PCI bridge [0604]: Freescale Semiconductor Inc P2020E [1957:0070] (rev 21) (prog-if 00 [Normal decode])
          Capabilities: [4c] Express Root Port (Slot-), MSI 00

Without any "Invalid class" error. So class code was properly reflected
into standard (read-only) PCI register 0x08.

Same fix is already implemented in U-Boot pcie_fsl.c driver in commit:
d18d06ac35

Fix activated by U-Boot stay active also after booting Linux kernel.
But boards which use older U-Boot version without that fix are affected and
still require this fix.

So implement this class code fix also in kernel fsl_pci.c driver.
