drm/amd/display: Increase compbuf size prior to updating clocks

Browse Source 
[WHY?]
Clocks are updating based on the incoming context's support, however the new
compbuf size is not programmed prior to udpating clocks, which can result in
P-State hangs.

[HOW?]
Increase compbuf size prior to updating clocks.
