drm/sysfb: corebootdrm: Add DRM driver for coreboot framebuffers

Add corebootdrm, a DRM driver for coreboot framebuffers. The driver
supports a pre-initialized framebuffer with various packed RGB formats.
The driver code is fairly small and uses the same logic as the other
sysfb drivers. Most of the implementation comes from existing sysfb
helpers.

Until now, coreboot relied on simpledrm or simplefb for boot-up graphics
output. Initialize the platform device for corebootdrm in the same place
in framebuffer_probe(). With a later commit, the simple-framebuffer should
be removed.

v4:
- sort include statements (Tzung-Bi)
v3:
- comment on _HAS_LFB semantics (Tzung-Bi)
- fix typo in commit description (Tzung-Bi)
- comment on simple-framebuffer being obsolete for coreboot
v2:
- reimplement as platform driver
- limit resources and mappings to known framebuffer memory; no
page alignment
- create corebootdrm device from coreboot framebuffer code

Merge tag 'drm-next-2025-05-28' of https://gitlab.freedesktop.org/drm/kernel

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.

The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.

There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.

Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
and msm being the main ones, and some changes to vsprintf.

new drivers:
- bring in the asahi uapi header standalone

drm/sysfb: Share helpers for screen_info validation

Share efidrm's and vesadrm's validation of struct screen_info in
shared helpers. Update the drivers.

Most validation helpers test individual values against limits and
can be shared as they are. For color formats, a common helper looks
up the correct DRM format info from a driver-provided list of color
formats.

These screen_info helpers are only available if CONFIG_SCREEN_INFO
has been selected, as done by efidrm and vesadrm.

There is existing support for these displays provided by simpledrm with

use of additional functionality provided by VESA, such as EDID information,
gamma correction and palette modes. This enhances the user experience and
adds support for more display configuratons.

drm/sysfb: Add efidrm for EFI displays

Add support for screen_info setups with VIDEO_TYPE_EFI. Provide the
minimum functionality of reading modes, updating and clearing the display.

There is existing support for these displays provided by simpledrm with
CONFIG_SYSFB_SIMPLEFB=y. Using efidrm over simpledrm will allows for the
mapping of video memory with correct caching. Simpledrm always assumes WC
caching, while fully cached memory is possible with efidrm. Efidrm will
also allow for the use of additional functionality provided by EFI, such
as EDID information.

In addition to efidrm, add struct pixel_format plus initializer macros.
The type and macros describe pixel formats in a generic way on order to
find the DRM format from the screen_info settings. Similar existing code
in SIMPLEFB_FORMATS and fbdev is not really what is needed in efidrm,
but SIMPLEFB_FORMATS can later be converted to struct pixel_format.

v4:
- depend on CONFIG_EFI
- disallow module for now as efi_mem_desc_lookup() is not exported
