images: fix force rebuild of piggy.o ...

piggy.o would be build for every time barebox was built
This had the sideeffect that the image(s) would
always be rebuilt despite no changes

Fix this by adding piggy.o to targets
and avoid an extra command in the rule to create .pblb files

The patch includes the removal of a stray assignment

Images: Add image size to built images ...

This brings back the image size written into the built images which got
lost in the conversion to using piggydata in the PBL images.

ARM: fix setup_c when runtime offset is != 0 ...

The runtime offset has to be added to the memcpy source address and
substracted from the return address. This should have been changed in
a43e2bbc46 which changed from returning the negative runtime offset
into changing the positive runtime offset. Instead a43e2bbc46 only
changed a zero substraction ("subs r4, r0, #0") into a zero addition
("adds r4, r0, #0") which was used as a equal to zero test and changed
nothing. This part is reverted here.

Fixes wrong copy / return locations when setup_c is called with
different runtime and link addresses.

fixes: a43e2bbc46 ("ARM: return positive offset in get_runtime_offset()")

globalvar: fix crash if CONFIG_NVVAR is not set ...

At the moment globalvar code tries to use nv_device
even if nv_device is not registered.

How to reproduce the problem:

    barebox$ make sandbox_defconfig
    ...
    barebox$ sed -i "s/\(CONFIG_NVVAR\)=y/# \1 is not set/" .config
    barebox$ sed -i "s/\(CONFIG_DEFAULT_ENVIRONMENT_GENERIC_NEW\)=y/# \1 is not set\n# CONFIG_DEFAULT_ENVIRONMENT_GENERIC is not set/" .config
    barebox$ make oldconfig
    ...
    barebox$ make
    ...
    barebox$ ./barebox
    Segmentation fault

This patch blocks nv_device use if CONFIG_NVVAR is not set.

of: Add .of suffix to device names from devicetree ...

Previous implementation used to add a number to the device names
for devices registered from the device tree which did not have a 'reg'
property, thus a device node named "state" resulted in a device name
"state.<x>". Current implementation skips that number and we get a
device named "state". This conflicts with our barebox state
implementation which tries to register a device named "state" itself.
We could rename the state device nodes of all our device trees, but it
causes less trouble to rename the devices.

This adds a ".of" suffix to the device names for devices registered from
the device tree which also has the nice effect that they now can easily
be recognized.

Fixes: 7e497d48acbd11 ("of: Port latest of_device_make_bus_id() implementation")
