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

+Subject: [PATCH 47/69] mtd: nand: Create a BBT flag to access bad block
+ markers in raw mode
+
+Some controllers can access the factory bad block marker from OOB only
+when they read it in raw mode. When ECC is enabled, these controllers
+discard reading/writing bad block markers, preventing access to them
+altogether.
+
+The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
+This results in the nand driver's ecc->read_oob() op to be called, which
+works with ECC enabled.
+
+Create a new BBT option flag that tells nand_bbt to force the mode to
+MTD_OPS_RAW. This would result in the correct op being called for the
+underlying nand controller driver.
