[U-Boot] [PATCH] ppc4xx: Enable NOR flash support in sequoia_ramboot target

Stefan Roese sr at denx.de

Until now, the Sequoia RAM-booting image disabled NOR flash support
as this image was mainly created for NAND-only boards. This patch
now enables NOR flash support for this RAM-booting version as well.
