apm821xx: add linux 4.14 apm821xx patches
This patch updates the apm821xx target to use the 4.14 kernel.
4.14 finally ships with a driver for the WNDR4700's tc654 fan
controller. The custom driver is deprecated in favor of the
upstream driver and the thermal cooling definitions in the DTS
are updated.
