generic: Convert incorrect generic/5.10 patches

OpenWRT's developer guide prefers having actual patches so they an be
sent upstream more easily.

However, in this case, Adding proper fields also allows for `git am` to
properly function. Some of these patches are quite old, and lack much
traceable history.

This commit tries to rectify that, by digging in the history to find
where and how it was first added.

It is by no means perfect and also shows some patches that should have
been long gone.

+Subject: [PATCH] kernel: fix FIT partition parser compatibility issues
+
+The uImage.FIT partition parser used to squeeze in FIT partitions in
+the range where partition editor tools (fdisk and such) expect the
+regular partition. This is confusing people and tools when adding
+additional partitions on top of the partition used for OpenWrt's
+uImage.FIT.
+Instead of squeezing in the additional partitions, rather start with
+all uImage.FIT partitions at offset 64.
