If "capacity-dmips-mhz" is present in a CPU DT node,
topology_parse_cpu_capacity() will fail to allocate memory. arm64, with
which this code path is shared, does not call
topology_parse_cpu_capacity() until later in boot where memory
allocation is available. While "capacity-dmips-mhz" is not yet a valid
property on RISC-V, invalid properties should be ignored rather than
cause issues. Move init_cpu_topology(), which calls
topology_parse_cpu_capacity(), to a later initialization stage, to match
arm64.
As a side effect of this change, RISC-V is "protected" from changes to
core topology code that would work on arm64 where memory allocation is
safe but on RISC-V isn't.
Fixes: 03f11f03db ("RISC-V: Parse cpu topology during boot.")
