rS354104: RISC-V: skip cpu-map when parsing elf_hwcap

Summary

The fill_elf_hwcap() function expects to find only cpu nodes under the
/cpus entry of the device tree. Newer versions of QEMU insert a cpu-map
node which describes the CPU topology, breaking this function. To fix
this, simply skip any non-cpu entries.
