drm/amd/amdgpu: Update debugfs link_settings output link_rate field in hex

Browse Source 
[ Upstream commit 1a394b3c3de2577f200cb623c52a5c2b82805cec ]

link_rate is updated via debugfs using hex values, set it to output
in hex as well.

eg: Resolution: 1920x1080@144Hz
cat /sys/kernel/debug/dri/0/DP-1/link_settings
Current:  4  0x14  0  Verified:  4  0x1e  0  Reported:  4  0x1e  16  Preferred:  0  0x0  0

echo "4 0x1e" > /sys/kernel/debug/dri/0/DP-1/link_settings

cat /sys/kernel/debug/dri/0/DP-1/link_settings
Current:  4  0x1e  0  Verified:  4  0x1e  0  Reported:  4  0x1e  16  Preferred:  4  0x1e  0
