Add code for mach-shmobile to allow specifying boot function and argument. Will initially be used for SMP together with SCU but may in the future also be used for deep sleep resume. This patch removes one inline virtual to physical address conversion. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
