Subject: [PATCH] drm/amd/pp: Send khz clock values to DC for smu7/8

The previous change wasn't covering smu 7 and 8 and therefore DC was
seeing wrong clock values.

This fixes an issue where the pipes seem to hang with a 4k DP and 1080p
HDMI display.

Fixes: c3df50abc84b ("drm/amd/pp: Convert clock unit to KHz as defined")
