Some board manufacturers hardcode the EDID for the embedded
panel in the VBIOS. This EDID should be used when the panel
doesn't have a DDC.
For reference, see the legacy non-DC display code:
amdgpu_atombios_encoder_get_lcd_info()
This is necessary to support embedded connectors without DDC.

the EDID may be hardcoded in ACPI or the VBIOS.
In this case, use GPIO_DDC_LINE_UNKNOWN and don't fail.

(cherry picked from commit 7f19097af1496dd908a044ca95862f32d05f02df)
[Why]
A previous warning-fix commit updated type casts in the DCN3
mmhubbub code but missed updating the MCIF_ADDR macro to the
correct, fully parenthesized and casted version. This caused
a regression during DWB tests, where address values could be
misinterpreted, potentially leading to incorrect hardware
programming.
[How]
Updated the MCIF_ADDR macro in dcn30_mmhubbub.c to use the
proper parenthesization and type casting, ensuring correct
address handling. Removed redundant casts from REG_UPDATE
calls for improved clarity and consistency with current
coding standards.

[WHY]
A situation has occurred where udl_handle_damage() executed successfully
and the kernel log appears normal, but the display fails to show any output.
This is because the call to udl_get_urb() in udl_crtc_helper_atomic_enable()
failed without generating any error message.
[HOW]
1. Increase timeout of getting urb.
2. Add error messages when calling udl_get_urb() failed in
udl_crtc_helper_atomic_enable().

drm_gem_fb_init_with_funcs() computes sub-sampled plane dimensions
using plain integer division:
unsigned int width = mode_cmd->width / (i ? info->hsub : 1);
unsigned int height = mode_cmd->height / (i ? info->vsub : 1);
However, the ioctl-level framebuffer_check() in drm_framebuffer.c uses
drm_format_info_plane_width/height() which round up dimensions via
DIV_ROUND_UP(). This inconsistency corrupts the subsequent GEM object
size check for certain pixel format and dimension combinations.
For example, with NV12 (vsub=2) and a 1-pixel-tall framebuffer the
GEM size validation path sees height=0 instead of height=1. The
expression (height - 1) then wraps to UINT_MAX as an unsigned int,
causing min_size to overflow and wrap back to a small value. A tiny
GEM object therefore passes the size guard, yet when the GPU accesses
the chroma plane it will read or write memory beyond the object's
bounds.
Fix by replacing the open-coded divisions with drm_format_info_plane_width()
and drm_format_info_plane_height(), which use DIV_ROUND_UP() and match
the calculation already used in framebuffer_check().
