[LEDE-DEV] [PATCH] ipq806x: add kernel 4.14 support

[Michael Yartys]

I tested the patch on the R7800 and I am experiencing the same issues with PCIe initialization (full dmesg output is attached):

Additionally, my kernel partition is expanded to 4 MB so I cannot comment on whether there are any issues with kernel size on the default 2 MB size.
