[ 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.
Fixes: 0484d3ce0902 ("arm64: dts: qcom: Add DTS for MSM8976 and MSM8956 SoCs")
Fixes: ff7f6d34ca07 ("arm64: dts: qcom: Add support for SONY Xperia X/X Compact")
