layerscape: update patches-4.14 to LSDK 19.03

All patches of LSDK 19.03 were ported to Openwrt kernel.
We still used an all-in-one patch for each IP/feature for
OpenWrt.

Below are the changes this patch introduced.
- Updated original IP/feature patches to LSDK 19.03.
- Added new IP/feature patches for eTSEC/PTP/TMU.
- Squashed scattered patches into IP/feature patches.
- Updated config-4.14 correspondingly.
- Refreshed all patches.
