ppc4xx: Add SPL support

This patch adds SPL booting support (NOR flash) for the
PPC4xx platforms.

This SPL booting (Falcon mode) will be used by the upcoming
lcd4_lwmon5 board port (lwmon5 variant).

Makefile: Add target for combined u-boot.img & spl/u-boot.bin

This new make target "u-boot-img-spl-at-end.bin" consists of the
the real, full-blown U-Boot image and the U-Boot SPL binary
directly attached to it. The full-blown U-Boot image has the
mkimage header included, with its load-address and entry-point.

This will be used by the upcoming lwmon5 PPC440EPx derivate board
port.

ppc4xx: Add lcd4_lwmon5 support

This patch adds the fast booting LWMON5 derivat "lcd4_lwmon5".
Its a stripped down version of the full blown lwmon5 support,
without ECC, USB, POST and some other stuff. It used the newly
introduced SPL infrastrucure for SPL from NOR flash booting
on the PPC4xx.

By setting the environment variable "boot_os" to "yes", Linux
will be started from the SPL version. If not, the "normal"
U-Boot will be started.

flash: Add optional verify-after-write feature

Sometimes it might make sense to verify the written data to NOR flash.
This patch adds this feature. To enable this verify-after-write, you
need to define CONFIG_FLASH_VERIFY in your board config header.

Please note that this option is useless in nearly all cases,
since such flash programming errors usually are detected earlier
while unprotecting/erasing/programming. Please only enable
this option if you really know what you are doing.
