If only linear modifier is advertised, since there are many drivers that
only linear supported, the DRM core should handle this rather than
open-coding in every driver. However, there are legacy drivers such as
radeon that do not support modifiers but infer the actual layout of the
underlying buffer. Therefore, a new flag fb_modifiers_not_supported is
introduced for these legacy drivers, and allow_fb_modifiers is replaced
with this new flag.
v3:
- change the order as follows:
1. add fb_modifiers_not_supported flag
2. add default modifiers
3. remove allow_fb_modifiers flag
- add a conditional disable in amdgpu_dm_plane_init()
v4:
- modify kernel docs
v5:
- modify kernel docs

According to disable Documentation/admin-guide/kernel-parameters.txt, this

DRM drivers will not perform display-mode changes or accelerated rendering
and only the system framebuffer will be available if it was set-up.
But only a few DRM drivers currently check for nomodeset, make this driver
to also support the command line parameter.

The commit feeb07d0ca ("drm/hisilicon/hibmc: Make CONFIG_DRM_HISI_HIBMC
depend on ARM64") made the driver Kconfig symbol to depend on ARM64 since
it only supports that architecture and loading the module on others would
lead to incorrect video modes being used.
But it also prevented the driver to be built on other architectures which
is useful to have compile test coverage when doing subsystem wide changes.
Make the dependency instead to be (ARM64 || COMPILE_TEST), so the driver
is buildable when the CONFIG_COMPILE_TEST option is enabled.
