This patch adds support for a generic MMU-less Nios II board that can
be used e.g. for bare-metal compiler testing with the linker script
and startup code provided by libgloss. Nios II booting is also
tweaked so that bare-metal binaries start executing in RAM starting at
0x00000000, rather than an alias at 0xc0000000, which allows features
such as unwinding to work when binaries are linked to start at the
beginning of the address space.
The generic_nommu.c parts are based on code by Andrew Jenner, which was
in turn based on code by Marek Vasut.

Original commit message:
This patch adds an emulation model for i2c controller found on most of the FSL SoCs.
It also integrates the RTC (ds1338) that sits on the i2c Bus with e500 machine model.
Patch was originally written by Amit Singh Tomar <amit.tomar@freescale.com>
see http://patchwork.ozlabs.org/patch/431475/
I only fixed it enough for application on top of current qemu master
20b084c4b1, and hopefully fixed checkpatch errors
Tested by booting Linux kernel 4.20.12. Now e500 machine doesn't need
network time protocol daemon because it will have working RTC
(before all timestamps on files were from 2016)

Instead of hard-coding all config switches in the config file
default-configs/s390x-softmmu.mak, let's use the new Kconfig files
to express the necessary dependencies: The S390_CCW_VIRTIO config switch
for the "s390-ccw-virtio" machine now selects all non-optional devices.
And since we already have the VIRTIO_PCI and VIRTIO_MMIO config switches
for the other two virtio transports, this patch also introduces a new
config switch VIRTIO_CCW for the third, s390x-specific virtio transport,
so that all three virtio transports are now handled in the same way.

The POWERNV switch should always select ISA_IPMI_BT, then the other
IPMI options are turned on automatically now.
CONFIG_DIMM should always be selected by the pseries machine,
which in turn depends on CONFIG_MEM_DEVICE since DIMM implements
this interface.

completely since this device is already automatically enabled via

-e'a\' -e' default y if PCI_DEVICES\' -e' depends on PCI' \

The make_device_config.sh script is replaced by minikconf, which
is modified to support the same command line as its predecessor.
The roots of the parsing are default-configs/*.mak, Kconfig.host and
hw/Kconfig. One difference with make_device_config.sh is that all symbols
have to be defined in a Kconfig file, including those coming from the
configure script. This is the reason for the Kconfig.host file introduced
in the previous patch. Whenever a file in default-configs/*.mak used
$(...) to refer to a config-host.mak symbol, this is replaced by a
Kconfig dependency; this part must be done already in this patch
for bisectability.
