[Qemu-devel] [PATCH v2 5/8] dtc: Update requirement to v1.4.2

[Paul Burton <paul.burton@imgtec.com>]

In order to obtain fdt_first_subnode & fdt_next_subnode symbols from
libfdt for use by a later patch, bump the requirement for dtc to v1.4.2
& the submodule to that same version.

Signed-off-by: Paul Burton <paul.burton@imgtec.com>

This will rely upon the dtc v1.4.2 tag being pushed to the dtc
repository on git.qemu.org.
