Revert "package/dtc: bump to v1.5.1"

This reverts commit 1e55b66e975d234f5bff992785762e8f7ee5f5b9.

This bump breaks the build of a number of defconfigs with errors like:

HOSTCC  scripts/dtc/libfdt/fdt_ro.o
scripts/dtc/libfdt/fdt_ro.c:92:10: error: redefinition of ‘fdt_get_max_phandle’
uint32_t fdt_get_max_phandle(const void *fdt)
^~~~~~~~~~~~~~~~~~~
In file included from scripts/dtc/libfdt/fdt_ro.c:54:
/work/beaglebone/host/include/libfdt.h:384:24: note: previous definition of ‘fdt_get_max_phandle’ was here

So revert it for 2019.11.

+Subject: [PATCH] Makefile: Add EXTRA_CFLAGS variable
+
+Distributions packaging dtc may need to set extra flags. Currently when
+they do that it overrides the ones set by the makefile. This is
+particularly problematic when compiling without yaml, as the yaml
+detection is ignored.
+
+ ld: dtc.o: in function `main':
+ dtc.c:(.text.startup+0x718): undefined reference to `dt_to_yaml'
+
+This patch provides a EXTRA_CFLAGS variable that is added to the list of
+CFLAGS, and can be set on the command line when packaging.
