Subject: [PATCH v2 2/4] asm-generic/io.h: Remove unused generic __ioremap()
 definition

Several arches use __ioremap() to help implement the generic ioremap(),
ioremap_nocache(), and ioremap_wc() interfaces, but this usage is all
inside the arch/ directory.

The only __ioremap() uses outside arch/ are in the ZorroII RAM disk driver
and some framebuffer drivers that are only buildable on m68k and powerpc,
and they use the versions provided by those arches.

There's no need for a generic version of __ioremap(), so remove it.
