This fixes printing clock names in cases like:
[    5.352311] [drm] DM_PPLIB: values for Invalid clock
[    5.352313] [drm] DM_PPLIB:   400000 in kHz
[    5.352313] [drm] DM_PPLIB:   933000 in kHz
[    5.352314] [drm] DM_PPLIB:   1067000 in kHz
[    5.352315] [drm] DM_PPLIB:   1200000 in kHz
[    5.352317] [drm] DM_PPLIB: values for Invalid clock
[    5.352318] [drm] DM_PPLIB:   300000 in kHz
[    5.352318] [drm] DM_PPLIB:   600000 in kHz
[    5.352319] [drm] DM_PPLIB:   626000 in kHz
[    5.352320] [drm] DM_PPLIB:   654000 in kHz
(source: HP EliteBook 745 G5 w. RAVEN 0x1002:0x15DD 0x103C:0x83D5 0xD1)

On my system above "Invalid" names got replaced by "F" and "DCF".

The same problem was occurring on Huawei Matebook D with just 667000 kHz
instead of 400000 kHz.
