ARM: dts: rmobile: Disable RPC HF by default
The RPC HF might be locked by ATF, and any access to its register
space would result in complete hang. Disable the RPC HF by default.
The ATF should be patched to set RPC node status = "okay" in the DT
fragment it passes to U-Boot in case the RPC HF access is unlocked,
and that way U-Boot could access the RPC HF safely.
