Subject: ARM: 7941/2: Fix incorrect FDT initrd parameter override

From: Ben Peddell <klightspeed@xxxxxxxxxxxxxxxx>

commit 4c235cb9e35407bdb4a2debeef4dc8721e8f91f2 upstream.

Commit 65939301acdb (arm: set initrd_start/initrd_end for fdt scan)
caused the FDT initrd_start and initrd_end to override the
phys_initrd_start and phys_initrd_size set by the initrd= kernel
parameter.  With this patch initrd_start and initrd_end will be
overridden if phys_initrd_start and phys_initrd_size are set by the
kernel initrd= parameter.

Fixes: 65939301acdb (arm: set initrd_start/initrd_end for fdt scan)
