Dan Carpenter 88cf81fc89 rapidio: use resource_size()
The size calculation is done incorrectly here because it should include
both the start and end (end - start + 1).  It's easiest to just use
resource_size() which does the right thing.

I was worried there was something non-standard going on because the
printk() subtracts "end - 1", but the rest of the file uses the normal
resource size calculations.  This function is only called from
fsl_rio_setup() in arch/powerpc/sysdev/fsl_rio.c and the calculation
there is also:

	port->iores.start = law_start;
	port->iores.end = law_start + law_size - 1;

So I think this is the correct fix.
