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 156/182] usb: dwc3: Add Qualcomm DWC3 glue layer driver
-
-DWC3 glue layer is hardware layer around Synopsys DesignWare
-USB3 core. Its purpose is to supply Synopsys IP with required
-clocks, voltages and interface it with the rest of the SoC.
