[PATCH 1/2] arm64: dts: qcom: msm8976: Add and provide xo clk to rpmcc

[Adam Skladowski <a39.skl@gmail.com>]

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")
