mpc85xx: add 3.14 kernel support for mpc85xx platform
This patch adds 3.14 kernel support for the mpc85xx platform. Works fine here with a TL-WDR4900 which seems to be the only supported device using this platform. There might be differences depending on HW version, therefore I'd ask others to test too. Changes to 3.10 missing config options added to 3.14 config file patch 001: rebased patch 100: rebased patch 110: rebased patch 120: rebased patch 130: rebased patch 140: minor adjustment patch 200: removed, change went upstream patch 210: rebased patch 220: removed, change went upstream patch 750: new, fixes an issue with ethernet port autoneg being disabled due to changes in kernel phy handling Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 43308

+Subject: spi-fsl-espi: avoid frequent high order allocations
+
+The driver allocates 64KiB of memory fro a local buffer before
+each transfer and releases that afterwards. When the memory is
+fragmented this allocation often fails and causes a warning like
+this:
+
