[PATCH] staging/nvec: Pass proper resource to mfd_add_devices()

[Thierry Reding <thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

The mfd_add_devices() parameter takes a struct resource * as fifth
argument, but the nvec driver passes in a void __iomem *. The driver
gets away with it because none of the subdevices ever directly access
the registers.

While at it, use platform_get_irq() instead of platform_get_resource()
to get the device's interrupt. This makes it easier to pass in the
register region since the variable is no longer reused.

Alternatively we could simply pass NULL into mfd_add_devices(), which
might be a slightly more accurate representation of what's going on.

Marc, Greg, any preferences?
