[meta-ti][master][PATCH] u-boot: fix pylibfdt build with swig 4.5.0

A recent change in oe-core [1] updated the version of SWIG which caused
a build error in u-boot.  This was fixed by adding a patch [2] in
oe-core for u-boot which we are copying into our u-boot recipes as well.

+Subject: [PATCH] pylibfdt: Replace removed SWIG Python 2 compatibility macros
+
+SWIG 4.5.0 removed Python 2 compatibility macros (PyInt_*, PyString_*)
+from its runtime header pyhead.swg (see commit 79f7a2b7cb7d). Replace
+them with their Python 3 C API equivalents:
+
+- PyString_FromString -> PyUnicode_FromString
+- PyString_AsString -> PyBytes_AsString
+- PyInt_AsLong -> PyLong_AsLong
+
+The replacements are safe since the macros were already aliased to
+these exact functions in SWIG's Python 3 code path.
+
+This is a backport of dtc commit 5008d1d6a356 ("pylibfdt: Replace
+removed SWIG Python 2 compatibility macros").
+
+Upstream-Status: Submitted [https://patchwork.ozlabs.org/patch/2283713/]
