target/riscv: Add a base 32 and 64 bit CPU

Browse Source 
At the same time deprecate the ISA string CPUs.

It is dobtful anyone specifies the CPUs, but we are keeping them for the
Spike machine (which is about to be depreated) so we may as well just
mark them as deprecated.

@section System emulator CPUS
@subsection RISC-V ISA CPUs (since 4.1)
The RISC-V cpus with the ISA version in the CPU name have been depcreated. The
four CPUs are: ``rv32gcsu-v1.9.1``, ``rv32gcsu-v1.10.0``, ``rv64gcsu-v1.9.1`` and
``rv64gcsu-v1.10.0``. Instead the version can be specified via the CPU ``priv_spec``
option when using the ``rv32`` or ``rv64`` CPUs.
