ipq806x: add kernel 4.14 support
- Rebased the patches for 4.14 - Dropped spi-qup and 0027, 0028, 0029 clk patches since it's already included in upstream. Tested on IPQ AP148 Board: 1) NOR boot and NAND boot 2) Tested USB and PCIe interfaces 3) WDOG test 4) cpu frequency scaling 5) ethernet, 2G and 5G WiFi 6) ubi sysupgrade Signed-off-by: Ram Chandra Jangir <rjangir@codeaurora.org> Tested-by: Stefan Lippers-Hollmann <s.l-h@gmx.de>
