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.

Add initializer macros for struct fb_ops for framebuffers in DMA-able
memory areas. Also add a corresponding Kconfig token. As of now, this
is equivalent to system framebuffers and mostly useful for labeling
drivers correctly.
A later patch may add a generic DMA-specific mmap operation. Linux
offers a number of dma_mmap_*() helpers for different use cases.

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags
has been allocated to zero by devm_kzalloc(). So do not set it.
Flags should signal differences from the default values. After cleaning
up all occurrences of FBINFO_DEFAULT, the token will be removed.

Backmerging to get v6.5-rc2.

Currently the CONFIG_FB option has to be enabled even if no legacy fbdev
drivers are needed (e.g: only to have support for framebuffer consoles).
The DRM subsystem has a fbdev emulation layer, but depends on CONFIG_FB
and so it can only be enabled if that dependency is enabled as well.
That means fbdev drivers have to be explicitly disabled if users want to
enable CONFIG_FB, only to use fbcon and/or the DRM fbdev emulation layer.
This patch introduces a non-visible CONFIG_FB_CORE symbol that could be
enabled just to have core support needed for CONFIG_DRM_FBDEV_EMULATION,
allowing CONFIG_FB to be disabled (and automatically disabling all the
fbdev drivers).
Nothing from fb_backlight.o and fbmon.o is used by the DRM fbdev emulation
layer so these two objects can be compiled out when CONFIG_FB is disabled.

The drivers/video/fbdev/Kconfig defines both symbols for fbdev drivers and
core fbdev symbols, that can be enabled independently of the fbdev drivers.
Split the Kconfig in two, one that only has the symbols for fbdev drivers
and another one that contains the fbdev core symbols.

git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v6.6:
UAPI Changes:
* fbdev:
* Make fbdev userspace interfaces optional; only leaves the
framebuffer console active
* prime:
* Support dma-buf self-import for all drivers automatically: improves
support for many userspace compositors
Cross-subsystem Changes:
* backlight:
* Fix interaction with fbdev in several drivers
* base: Convert struct platform.remove to return void; part of a larger,
tree-wide effort
* dma-buf: Acquire reservation lock for mmap() in exporters; part
of an on-going effort to simplify locking around dma-bufs
* fbdev:
* Use Linux device instead of fbdev device in many places
* Use deferred-I/O helper macros in various drivers
* i2c: Convert struct i2c from .probe_new to .probe; part of a larger,
tree-wide effort
* video:
* Avoid including <linux/screen_info.h>
Core Changes:
