[PATCH] arm: omap: Use resource_size

[Tony Lindgren]

* Tobias Klauser <tklauser at distanz.ch> [091109 09:44]:
> Use the resource_size function instead of manually calculating the
> resource size. This reduces the chance of introducing off-by-one errors
> and actually fixes one in mailbox.c.
> 
> Signed-off-by: Tobias Klauser <tklauser at distanz.ch>
