[ Upstream commit 4a2c9b9e1215c557c17a48e3fabe9b1674c1d608 ]
In order for consumers of RPMCC XO clock to probe successfully their parent needs to be feed with reference clock to obtain proper rate, add fixed xo-board clock and supply it to rpmcc to make consumers happy. Frequency setting is left per board basis just like on other recent trees.
