vfio-dev/mdpy-fb: Use fbdev I/O helpers
Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer for I/O memory. Sets the callbacks to the cfb_ and fb_io_ functions. Select the correct modules with Kconfig's FB_IOMEM_HELPERS token. The macro and token set the currently selected values, so there is no functional change. v3: * use _IOMEM_ in commit message v2: * updated to use _IOMEM_ tokens Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Helge Deller <deller@gmx.de> Cc: Kirti Wankhede <kwankhede@nvidia.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230803184034.6456-48-tzimmermann@suse.de
