[PATCH 3/3] arm64: dts: qcom: glymur: Tie up the CX power domain to GCC

[Abel Vesa]

It has been concluded off-list that the Global Clock Controller needs to
scale the RPMh CX power domain, otherwise some of the subsystems might
crash or be unstable. So adding the RPMh CX power domain to the clock
controller which will result in all GDSCs being parented by CX. This way,
the vote from the consumers of each GDSC will trickle all the way to CX.

So add the power domain and Make sure the required OPP is nominal.
