uboot-imx6: bump to 2020.01 and refresh patches

Update U-Boot to latest release, remove `100-wandboard-enable-fit.patch`
as FIT support was added in commit 5b8585825128 ("wandboard: Add FIT
image support").

Rework `110-mx6cuboxi-mmc-fallback.patch` into two patches as there was
new config option `CONFIG_SPL_FORCE_MMC_BOOT` added upstream which
should provide the same functionality as the previous patch hunk.

Moving Apalis towards generic distro_bootcmd.

-Subject: [PATCH] imx6: apalis: Make the boot process more generic
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-I'm preparing support for Apalis imx6 boards in OpenWrt and I've ended
-up with quite huge patchset against upstream U-Boot 2018.03, so I'm
-trying to propose more generic way of boot process handling.
-
-In OpenWrt we usually have kernel, dtbs and U-Boot boot script in boot
-partition with ext4fs, so for some use cases it would be handy to be
-able to replace some of the files in the boot partion, that's why I've
-added write support to the ext4.
-
-I've added `set_blkcnt` environment variable which is needed for every
-`mmc write` command as we need to always specify size in block count.
-This is copy&pasted from official Toradex's flashing scripts, so all the
-credits for this work belongs to them.
-
-Currently the rootfs location is passed via mmcblk number and the
-problem with this approach is that the mmcblk number for the boot device
-changes depending on the kernel version and imx6 SoC type.  In order to
-avoid such issues, use the UUID method to specify the rootfs location.
-
-I've added new boot sequence, where we first try to load and run boot
-script defined in the new `script` variable, so the boot process could
-be more generic and overridden by the distro. When the boot script isn't
-loaded, it will use the previous boot sequence so it should be backward
-compatible.
-
-For the recovery purposes and better end user experience I've added boot
-from SDP as the last boot command if every other boot option fails. I
-plan to use SDP as official flashing/recovery procedure in OpenWrt for
-Apalis imx6 boards.
-
-I've copy&pasted almost everything from the `f086812a mx6sxsabresd: Use
-PARTUUID to specify the rootfs location` commit, so credits for the rest
-of this patch belongs to Fabio.
