Without this, after the first build of wrpc-sw the ppsi
configuration was never changed.

So if you built e.g. "gsi_defconfig" and then reconfigure
for "gsi_pdelay_defconfig" you'll get no pdelay in there.

For me, and the next maintainers of ppsi, the new configuration option
CONFIG_PPSI_FORCE_CONFIG can be unset in order to test with personale
changes in ppsi configuration.

Also, preserve and restore current configuration, so I don't get mad
when checking with MAKEALL during my tests for new feature.

The rationale for this is that wrpc-sw will soon select different ppsi
choices according to its own configuration, through $(PPSI-CFG-y).
Actually, it already does for the host process build.

MAKEALL must obey this choice, so we trim ppsi configuration
each time we reconfigure wrpc (removing the file would spit an
error instead).

Then, our Makefile forces a ppsi reconfig if ppsi/.config is missing
*or* empty.

The new config tools are more picky. We got:

   Kconfig:22:warning: defaults for choice values not supported

and

  warning: (WR_SWITCH) selects UART which has unmet direct dependencies
             (DEVELOPER && EMBEDDED_NODE)

The latter is fixed adding WR_SWITCH in the dependencies. The former
is worked-around by using "IS_XINT" and friends in "choice", and
then "XINT" replicates the "IS_" choice.  I dislike it, because it's
repetition, but we really need CONFIG_PRINTF_XINT and friends in

Now it is also possible to use for dot-config configuration:
make nconfig

kconfig is taken from the linux kernel repo commit v4.8-rc1-19-g81abf25:

It does not make sense when the init is stored in flash and the board has no
EEPROM. Otherwise, storage_init() calls mi2c_devprobe() if needed.
