The ioread32() and iowrite32() I/O accessors are not available on all
architectures. Replace them with readl() and writel() to avoid
compilation failures. Although VSP1 devices are only available on
Renesas ARM platforms, allowing the driver to compile on all
architectures is useful to catch compilation-time issues.

This fix is a candidate for v3.12, as building the kernel with allyesconfig
on architectures without ioread32/iowrite32 support currently fails on
v3.12-rc5.
I'll send a pull request to the media tree shortly along with another v3.12
fix that has previously been posted to the linux-media mailing list.
