Old Kernel e.g. 5.10.23 initializes this

[    1.992385] kernel: [drm] DM_PPLIB: values for DCF clock
[    1.992387] kernel: [drm] DM_PPLIB:         300000 in kHz, 2874 in mV
[    1.992388] kernel: [drm] DM_PPLIB:         600000 in kHz, 3224 in mV
[    1.992390] kernel: [drm] DM_PPLIB:         626000 in kHz, 3924 in mV
[    1.992391] kernel: [drm] DM_PPLIB:         654000 in kHz, 4074 in mV
So I think this is related as the new kernel driver can`t initialize the values
for the discrete card.
Please fix.
