drm/omapdrm: Fix console with deferred ops

[ Upstream commit 01c0cce88c5480cc2505b79330246ef12eda938f ]

Commit 95da53d63dcf ("drm/omapdrm: Use regular fbdev I/O helpers")
stopped console from updating for command mode displays because there is
no damage handling in fb_sys_write() unlike we had earlier in
drm_fb_helper_sys_write().

Let's fix the issue by adding FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS and
FB_DMAMEM_HELPERS_DEFERRED as suggested by Thomas. We cannot use the
FB_DEFAULT_DEFERRED_OPS as fb_deferred_io_mmap() won't work properly
for write-combine.

fbdev: Provide I/O-memory helpers as module

[ Upstream commit 6b180f66c0dd6266eeb2f74b59ee79a9f14fe430 ]

Provide helpers for accessing I/O memory in a helper module. The fbdev
core uses these helpers, so select the module unconditionally for fbdev.
Drivers will later be able to select the module individually and the
helpers will become optional.

drm: fix up fbdev Kconfig defaults

As a result of the recent Kconfig reworks, the default settings for the
framebuffer interfaces changed in unexpected ways:

Configurations that leave CONFIG_FB disabled but use DRM now get
DRM_FBDEV_EMULATION by default. This also turns on the deprecated /dev/fb
device nodes for machines that don't actually want it.

In turn, configurations that previously had DRM_FBDEV_EMULATION enabled
now only get the /dev/fb front-end but not the more useful framebuffer
console, which is not selected any more.

We had previously decided that any combination of the three frontends
(FB_DEVICE, FRAMEBUFFER_CONSOLE and LOGO) should be selectable, but the
new default settings mean that a lot of defconfig files would have to
get adapted.

Change the defaults back to what they were in Linux 6.5:

- Leave DRM_FBDEV_EMULATION turned off unless CONFIG_FB
is enabled. Previously this was a hard dependency but now the two are
independent. However, configurations that enable CONFIG_FB probably
also want to keep the emulation for DRM, while those without FB
presumably did that intentionally in the past.

- Leave FB_DEVICE turned off for FB=n. Following the same
logic, the deprecated option should not automatically get enabled
here, most users that had FB turned off in the past do not want it,
even if they want the console

- Turn the FRAMEBUFFER_CONSOLE option on if
DRM_FBDEV_EMULATION is set to avoid having to change defconfig
files that relied on it being selected unconditionally in the past.
This also makes sense since both LOGO and FB_DEVICE are now disabled
by default for builds without CONFIG_FB, but DRM_FBDEV_EMULATION
would make no sense if all three are disabled.

fbdev: Add fb_ops init macros for framebuffers in DMA-able memory

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.

fbdev: Split frame buffer support in FB and FB_CORE symbols

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.

fbdev: Move core fbdev symbols to a separate Kconfig file

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.
