msm: spm_devices: Do not use predetermined logical ids for CPUs

The logical ids of CPUs can be altered during boot up in the linux
bootloaders and the drivers cannot rely on logical CPUids hardcoded into
the device tree.  Remove support "qcom,core-id" and "qcom,vctl-cpu-mask",
    which were used for on targets where CPU phandles weren't available.

These targets are not longer supported with the existing code base and the
driver expects phandles to identify the CPU that is associated with a CPU.
In scenarios where the CPU phandle isn't associated with a physical CPU,
   these devices are ignored and not probed.
