[RFC PATCH 05/16] tile: provide default ioremap declaration

[Logan Gunthorpe <logang@deltatee.com>]

Add a default ioremap function which was not provided in all
circumstances. (Only when CONFIG_PCI and CONFIG_TILEGX was set).

I have designs to use them in scatterlist.c where they'd likely never
be called with this architecture, but it is needed to compile.
