61bf32937b drm/amd/display: dc/irq: add support for DCE6 (v4) 
[Why]
irq service requires changes for DCE6 support

[How]
(v1) DCE6 targets are added replicating existing DCE8 implementation.
     due to missing CRTC_VERTICAL_INTERRUPT0_CONTROL registers/masks,
     dce/dce_8_0_{d,sh_mask}.h used instead of dce/dce_6_0_{d,sh_mask}.h

(v2) DCE6 headers used adding the necessary vblank irq registers
     (INT_MASK and VBLANK_STATUS) and vblank irq masks as implemented
     in amdgpu driver.
     Add vblank_irq_info_funcs_dce60 with .set and .ack as per commit
     b10d51f ("drm/amd/display: Add interrupt entries for VBLANK isr.")
     and use it in vblank_int_entry(reg_num) macro definition

(v3) updated due to following kernel 5.3 commit:
     4fc4dca ("drm/amd: drop use of drmp.h in os_types.h")

(v4) updated due to following kernel 5.6 commit:
     d9e3267 ("drm/amd/display: cleanup of construct and destruct funcs")

b86a1aa36a drm/amd/display: rename DCN1_0 kconfig to DCN 
Since dcn20 and dcn21 are under dcn1 it doesnt make sense to
have it named dcn1.

Change it to "dcn" to make it generic

4fc4dca832 drm/amd: drop use of drmp.h in os_types.h 
Drop use of the deprecated drmP.h from display/dc/os_types.h

Fix all fallout after this change.
Most of the fixes was adding a missing include of vmalloc.h.

dc37a9a08d Revert "drm/amdgpu/display: Replace CONFIG_DRM_AMD_DC_DCN1_0 with CONFIG_X86" 
This reverts commit 8624c3c4dbfe24fc6740687236a2e196f5f4bfb0.

We need CONFIG_DRM_AMD_DC_DCN1_0 to guard code that is using fp math.

5d908944c5 drm/amd/display: off by one in find_irq_source_info() 
The ->info[] array has DAL_IRQ_SOURCES_NUMBER elements so this condition
should be >= instead of > or we could read one element beyond the end of
the array.
