<content type='text'>
[Why &amp; How]
CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC
code should be OS-agnostic.

This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN
in irq directory.

Remove the unused struct irq_source_info_funcs

hooked up.

This was pointed by clang with the following warning:

The WA from commit 2a50edbf10c8 ("drm/amd/display: Apply w/a for hard hang
on HPD") and commit 1bd3bc745e7f ("drm/amd/display: Extend w/a for hard
hang on HPD to dcn20") causes a regression in s0ix where the system will
fail to resume properly on many laptops.  Pull the workarounds out to
avoid that s0ix regression in the common case.  This HPD hang happens with
an external device in special circumstances and a new W/A will need to be
developed for this in the future.

[Why]
Current error log of dummy irq service doesn't have
src/ext ID info in the log.

[How]
Add src/ext ID in ack/set of dummy irq service.

This turns previously global functions into static, thus removing
compile-time warnings such as:

 warning: no previous prototype for 'get_highest_allowed_voltage_level'
 [-Wmissing-prototypes]
 742 | unsigned int get_highest_allowed_voltage_level(uint32_t chip_family, uint32_t hw_internal_rev, uint32_t pci_revision_id)
     |              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 warning: no previous prototype for 'rv1_vbios_smu_send_msg_with_param'
 [-Wmissing-prototypes]
 102 | int rv1_vbios_smu_send_msg_with_param(struct clk_mgr_internal *clk_mgr, unsigned int msg_id, unsigned int param)
     |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Changes since v1:
- As suggested by Rodrigo Siqueira:
  1. Rewrite function signatures to make them more readable.
  2. Get rid of unused functions in order to remove 'defined but not
     used' warnings.
