Subject: [PATCH 12/15] arm64: dts: qcom: sm6125: Switch fixed xo_board
 clock to RPM XO clock

We have a working RPM XO clock; no other driver except rpmcc should be
parenting directly to the fixed-factor xo_board clock nor should it be
reachable by that global name.  Remove the name to that effect, so that
every clock relation is explicitly defined in DTS.
