    arm64: dts: qcom: msm8976: Add and provide xo clk to rpmcc
    
    [ 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.
