[PATCH 02/15] ARM: shmobile: Let romImage rely on default ATAGS

From: Magnus Damm <damm at opensource.se>
Remove the ATAGS data structure from head-shmobile.S
since a default ATAGS is already provided by the code
in arch/arm/kernel/atags_parser.c. Passing a NULL as
ATAGS is valid. For actual hardware specific setup
the fixup callback in the board code may be used.
