Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

Instead of modifying the value member of a list element passed as a
parameter, and open-coding the manipulation of that list, it's nicer
to just return a freshly allocated value to be prepended to a list
using QAPI_LIST_PREPEND.

Instead of using string compares to determine if a RISC-V machine is
using 32-bit or 64-bit CPUs we can use the initalised CPUs. This avoids
us having to maintain a list of CPU names to compare against.
This commit also fixes the name of the function to match the
riscv_cpu_is_32bit() function.

Since NVDIMM support was introduced on pseries machine,
it ignored machine's nvdimm=on|off option and effectively
was always enabled on machines that support NVDIMM.
Later on commit
(28f5a71621 ppc/spapr_nvdimm: do not enable support with 'nvdimm=off')
makes QEMU error out in case user explicitly set 'nvdimm=off'
on CLI by peeking at machine_opts.
However that's a workaround and leaves 'nvdimms_state->is_enabled'
in inconsistent state (false) when it should be set true
by default.
Instead of using on machine_opts, set default to true for pseries
machine in initfn time. If user sets manually 'nvdimm=off'
it will overwrite default value to false and QEMU will error
as expected without need to peek into machine_opts.
That way pseries will have, nvdimm enabled by default and
will honor user provided 'nvdimm=on|off'.

machine_init_done is not the right flag to check when preconfig
