drm/i915/bios: tidy up child device debug logging

Make the child device details easier to read by turning this:

[drm:parse_ddi_port [i915]] Port B VBT info: CRT:0 DVI:1 HDMI:1 DP:0 eDP:0 LSPCON:0 USB-Type-C:0 TBT:0 DSC:0
[drm:parse_ddi_port [i915]] VBT HDMI level shift for port B: 8
[drm:parse_ddi_port [i915]] VBT DP max link rate for port B: 810000
[drm:parse_ddi_port [i915]] Port C VBT info: CRT:0 DVI:1 HDMI:1 DP:1 eDP:0 LSPCON:0 USB-Type-C:0 TBT:0 DSC:0
[drm:parse_ddi_port [i915]] VBT HDMI level shift for port C: 8
[drm:parse_ddi_port [i915]] VBT (e)DP boost level for port C: 3
[drm:parse_ddi_port [i915]] VBT HDMI boost level for port C: 1
[drm:parse_ddi_port [i915]] VBT DP max link rate for port C: 810000

into this:

[drm:parse_ddi_port [i915]] Port B VBT info: CRT:0 DVI:1 HDMI:1 DP:0 eDP:0 LSPCON:0 USB-Type-C:0 TBT:0 DSC:0
[drm:parse_ddi_port [i915]] Port B VBT HDMI level shift: 8

[drm:parse_ddi_port [i915]] Port C VBT info: CRT:0 DVI:1 HDMI:1 DP:1 eDP:0 LSPCON:0 USB-Type-C:0 TBT:0 DSC:0
[drm:parse_ddi_port [i915]] Port C VBT HDMI level shift: 8
[drm:parse_ddi_port [i915]] Port C VBT (e)DP boost level: 3
[drm:parse_ddi_port [i915]] Port C VBT HDMI boost level: 1
[drm:parse_ddi_port [i915]] Port C VBT DP max link rate: 810000
