John Crispin 1175e83f50 mpc85xx: add 3.19 support
It took very little to make the TL-WDR4900 work under 3.19:
- config is the same as for 3.18
- only patch 210 had to be refreshed, the other patches are
  the same as for 3.18
- in /etc/config/wireless the path options need to be prefixed
  with "platform/" ('platform/ffe09000.pci/...')
