[PATCH 4/4] drm: add convert_lines_toio() variant, fix cirrus builds on powerpc.
The __io_virt() macro is not available on all architectures, so cirrus
can't simply pass a pointer to io memory down to the format conversion
helpers. The format conversion helpers must use memcpy_toio() instead.
Add a convert_lines_toio() variant which does just that. Switch the
drm_fb_*_dstclip() functions used by cirrus to accept a __iomem pointer
as destination and pass that down to convert_lines_toio(). Fix the
calls in the cirrus driver to not use __io_virt() any more.
