drm/radeon: fix audio dto calculation on DCE3+ (v3)
Need to set the wallclock ratio and adjust the phase and module registers appropriately. May fix problems with audio timing at certain display timings.
v2: properly handle clocks below 24mhz v3: rebase r600 changes
Tested with 44,1k and 48k source, screen 50Hz.

--- Comment #1 from Andy Furniss adf.lists@gmail.com --- More testing shows that low Hz modes do still work - in all cases the /1.001 modes behave the same as the exacts.
50p and 60p = fail = no sound and mplayer behaves as is does if the device isn't there = playing too fast.
24p, 25i and 30i are working OK.

--- Comment #2 from Alex Deucher agd5f@yahoo.com --- Possibly related to bug 69675? Does reverting e6e792092e816bea0797995c886fb057c91d4546 also fix the issue?

I may try later but TBH I can't see why it would, the new modes seem to be just extras that don't alter the original modes or even add one in the 50Hz case and they all work for me before 1518dd8efd47918bb269f1470030592875953f6c anyway.
