[ Upstream commit e8dca30f7118461d47e1c3510d0e31b277439151 ]
CTA-861-F explicitly states that for RGB colorspace colorimetry should
be set to "none". Fix that.

[ Upstream commit 063e768ebd27d3ec0d6908b7f8ea9b0a732b9949 ]
This can fix the baco reset failure seen on Navi10.
And this should be a low risk fix as the same sequence
is already used for system suspend/resume.

[ Upstream commit dec9de2ada523b344eb2428abfedf9d6cd0a0029 ]
This fixes a problem found on the MacBookPro 2017 Retina panel:
The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec aka LINK_RATE_RBR2
aka 0xc), but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.
This restricts the panel to 8 bpc, not providing the full
color depth of the panel on Linux <= 5.5. Additionally, commit
'4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")'
introduced into Linux 5.6-rc1 will unclamp panel depth to
its full 10 bpc, thereby requiring a eDP bandwidth for all
modes that exceeds the bandwidth available and causes all modes
to fail validation -> No modes for the laptop panel -> failure
to set any mode -> Panel goes dark.
This patch adds a quirk specific to the MBP 2017 15" Retina
panel to override reported max link rate to the correct maximum
of 0xc = LINK_RATE_RBR2 to fix the darkness and reduced display
precision.
Please apply for Linux 5.6+ to avoid regressing Apple MBP panel
support.

[ Upstream commit 8c34cd1a7f089dc03933289c5d4a4d1489549828 ]
Shutdown of firmware framebuffer has a bunch of problems. Because
of this the framebuffer region might still be reserved even after
drm_fb_helper_remove_conflicting_pci_framebuffers() returned.
Don't consider pci_request_region() failure for the framebuffer
region as fatal error to workaround this issue.

drm_lease_create takes ownership of leases. And leases will be released
by drm_master_put.
drm_master_put
->drm_master_destroy
->idr_destroy
So we needn't call idr_destroy again.
