Obsoletes my Ethernet patch.

Changes in v7:
- fix eth: added clock assignement for phy.
  It gets clock from PLL4_P which must be configured
  in u-boot/ATF as stmicroelectronics suggests.

This build no longer requires an initramfs. It has hence been removed entirely. The associated defconfig is deleted, as are the postbuild and postimage scripts and overlays. The patches have been relocated to the rootfs_patches directory. Also worth noting is that the machine-id setup is entirely gone from the build system.
