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.
