This allows other driver to reuse the name string for spi-altera
platform device creation.

This is a very unusual thing to do, normally we just have the users use
the strong directly.  It feels like if we are going to change this idiom
we should do so globally but that seems like far more trouble thanit's
worth.

Sure, I'll discard this patch and just use string for spi-altera device
creation.

Thanks,
Yilun.
