libre: Merge uboot4extlinux{am335x,omap3}, uboot-omap4_panda: into uboot4extlinux-ti-soc

uboot4extlinux-am335x and uboot4extlinux-omap3 were almost identical, the
only difference was the extlinux.conf file. So they were migrated together
in a single package for all TI SOCs.

I think having a single package saves maintenance time: We only have one
package to update for all the supported boards.

One downside is that it can increase the compilation time, but in overal it
probably saves a lot of time.

Another downside is that we cannot test the package separately for each
boards and have to test all the boards for each new update. However since
we are very close to upstream u-boot, there is very few probability of
having breakages that we don't know about. Factorizing the package can also
increase confidence that it will work on the boards we don't have, by
testing on the boards we have.

For instance I've only been able to test this package on the following
boards as I don't have any of the other boards:
- Beagleboard XM
- Beaglebone Green

The support for the Pandaborad from uboot-omap4_panda was added along the
way to furthurer unify u-boot packages.

In addition the version was updated and some whitespace fixes were done.

+Subject: [PATCH] omap34xx: SPL: enable MMC raw boot with u-boot.img
+
+The following commit enabled raw SPL booting:
+  22d90d560a omap3: Use raw SPL by default for mmc1
+but it was reverted by the following commit:
+  821c89d38c Revert "omap3: Use raw SPL by default for mmc1"
+because SPL is unable to distinguish between RAW images and
+garbage.
+
+However if CONFIG_SPL_RAW_IMAGE_SUPPORT is disabled, SPL does
+identify if there is a valid image with spl_parse_image_header.
+
+With this change, and CONFIG_SPL_RAW_IMAGE_SUPPORT disabled,
+raw MMC boot will be tried first, and if it fails, it FS will
+be tried.
+
+The two scenarios have been tested on a BeagleBoard XM Revision C1.
