In preparation for offering variation to our build configurations lets
move everything and rename it to default. Common included base configs
are also renamed.

During the cleanup the stale usb.mak and pci.mak references were
removed from MAINTAINERS.

We currently select CONFIG_V7M for a bunch of our m-profile devices.
The last sticking point is translate.c which cannot be compiled
without expecting v7m support. Express this dependency in Kconfig
rather than in default devices as a stepping stone to a fully
configurable translate.c.

While we are at it we also need to select ARM_COMPATIBLE_SEMIHOSTING
as that is implied for M profile machines.

Add a target-specific Kconfig. We need the definitions in Kconfig so
the minikconf tool can verify they exits. However CONFIG_FOO is only
enabled for target foo via the meson.build rules.

Two architecture have a particularity, ARM and MIPS. As their
translators have been split you can potentially build a plain 32 bit

Coverity reports that qemu_parse_config_group is returning without
unrefing the "crumpled" dictionary in case its top level item is a
list.  But actually the contract with qemu_record_config_group is
the same as for qemu_parse_config_group itself: if those function
need to stash the dictionary they get, they have to take a reference
themselves (currently this is never the case for either function).
Therefore, just add an unconditional qobject_unref(crumpled) to
qemu_parse_config_group.
