Why are you using a nonstandard property for the address?
AFAICT, the same can be expressed normally doing
mcc {
#address-cells = <2>;
#size-cells = <0>;
arm,vexpress,config-bridge = <&v2m_sysreg>;
osc at 0 {
compatible = "arm,vexpress-osc";
reg = <1 0>;
};
};
which is more in line with how we represent e.g. i2c buses.
