configs/mx6sx_udoo_neo: Bump to U-Boot 2017.01
Bump to U-Boot 2017.01, which supports mx6sx_udoo_neo by default.
Remove the U-Boot patch that we used for the previous version.
Also adjust the 'fdtfile' name as it has been changed in U-Boot
mainline.
[Peter: part 2, boot.scr / defconfig changed accidently got dropped]
