Subject: [PATCH v2 7/8] ARM: dts: arm: Update ICST clock nodes 'reg' and node names
Add a 'reg' entry for ICST clock nodes on the Arm Ltd platforms. The 'reg'
entry is the VCO register address. With this, the node name can be updated
to use a generic node name, 'clock-controller', and a unit-address.
