ipq806x: update target to v3.18

Patches in the ipq806x/patches folder were out of tree in v3.14. The
newest patch at the time was from June, so we can safely assume that
either the patches have been merged, or they have been rejected for
a good reason. If patches are seen missing, we'll cherry-pick them
on a per-needed basis.

This new kernel have been tested on AP148, which seems to works fine.

-Subject: [PATCH 109/182] libahci: Allow drivers to override start_engine
-
-Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which needs a
-special register to be poked before starting the DMA engine.
-
-This register gets reset on an ahci_stop_engine call, so there is no other
-place then ahci_start_engine where this poking can be done.
-
-This commit allows drivers to override ahci_start_engine behavior for use by
-the Allwinner AHCI driver (and potentially other drivers in the future).
