Call USBD_Disconnect before software-triggered CPU reset

This makes sure that we'll re-enumerate on the USB, as a CPU reset
apparently doesn't automatically release the pull-up and notify the hub
that we were gone?

For some strange reason my output is garbled in both the 'screen' and

understand why, but let's simply adjust the code as needed for now.

fix g_dfu access from both DFU and runtime access
...
We need to refer to g_dfu as a pointer from all code. In DFU mode, it
gets assigned to the address of _g_dfu, which is placed by the linker
script at the start of RAM. In runtime mode, the pointer is statically
defined to point at the start of RAM. The linker script for the runtime
(dfu environment) is adjusted to save the first 32 bytes for the _g_dfu
structure.

This way we can easily check with 'diff' for differences in our code and
Atmel softpack. Also, this layout is more suitable for building various
different firmware images (e.g. factory-test, dfu-loader, main
application) for a variety of different boards (simtrace, owhw, qmod).

Extend WWAN modem PERST to 300ms
...
It seems like a lot of modems have rather long (100ms!) minimum reset
durations. Makes me wonder if it's an actual reset line or rather juts
some GPIO that they poll/sample every so often. Then there are other
modems that state the reset *must not* be longer than 1s. So let's
choose 300ms as a value in-between.
