layerscape: upgrade kernel to 4.14

This patch is to upgrade kernel to 4.14 for layerscape.
patches-4.14 for layerscape included two categories.

- NXP Layerscape SDK kernel-4.14 patches

  All patches on tag LSDK-18.09-V4.14 were ported to OpenWrt
  kernel. Since there were hundreds patches, we had to make
  an all-in-one patch for each IP/feature.
  See below links for LSDK kernel.
  https://lsdk.github.io/components.html
  https://source.codeaurora.org/external/qoriq/qoriq-components/linux

- Non-LSDK kernel patches

  Other patches which were not in LSDK were just put in patches-4.14.
  Kept below patches from patches-4.9.
  303-dts-layerscape-add-traverse-ls1043.patch
  821-add-esdhc-vsel-to-ls1043.patch
  822-rgmii-fixed-link.patch

  Renamed and rebase them as below in patches-4.14,
  303-add-DTS-for-Traverse-LS1043-Boards.patch
  712-sdk-dpaa-rgmii-fixed-link.patch
  824-mmc-sdhci-of-esdhc-add-voltage-switch-support-for-ls.patch
