libre: uboot4extlinux-am335x: sync with sunxi and update to 2019.01
0001-parabola-arm-modifications.patch was removed because: - CONFIG_DISTRO_DEFAULTS=y is in am335x_evm_defconfig - #include <config_distro_bootcmd.h> is in am335x_evm.h More details are available in doc/README.distro in the u-boot source code.
