nouveau/instmem: use iomapping interface for instmem handling

This avoids constant need to ioremap when instobjs move at least on
64-bit systems.

This create the io mapping on first use, because creating it at init
time causes a resource mapping error, because nouveau hasn't kicked
simpledrm off the hardware yet, but ioremap_wc the whole BAR causes an
overlap with BOOTFB/simpledrm. I think the resource system could do
better here, but it's easier to just delay creating the mapping until
first use.
