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/...')

+Subject: [PATCH] mpc85xx: add mpic timer clock frequency
+
+MPIC timers are enabled in the config, however a devicetree clock setting
+is missing causing the following error:
+/soc@ffe00000/timer@41100: cannot get timer frequency.
+/soc@ffe00000/timer@42100: cannot get timer frequency.
+
+This patch adds the missing clock and avoids the error.
+It's a functional copy of this code
+do_fixup_by_compat_u32(blob, "fsl,mpic",
+	"clock-frequency", get_bus_freq(0), 1);
+in arch/powerpc/cpu/mpc85xx/fdt.c in the u-boot code.

+From: Gabor Juhos <juhosg@openwrt.org>
+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:
+
+  kworker/u2:2: page allocation failure: order:4, mode:0x10c0d0
