[RESEND PATCH 00/16] Nokia RX-51: Fix USB TTY console and enable it

[Pali Rohár]

This series contain resensed patches from two patch series:
* Nokia RX-51: Fix USB TTY console and enable it
* usbtty/musb: Fix file transfers
They are rebased on top of master branch.

This patch series fix usbtty code (serial console via USB peripheral
mode), fix underlying musb peripheral code, fix compilation of
CONFIG_USB_DEVICE (used by usbtty), remove unused Nokia RX-51 code to
decrease size of U-Boot binary and finally enable usbtty serial console
for Nokia RX-51.

With this patch series debugging of Nokia RX-51 can be done also via USB
serial console.

It fixes also stability of musb code and allows usage of file transfers
via Kermit protocol on Nokia RX-51. Kermit file transfer via U-Boot loadb
command is stable on Nokia N900 and gives about 52kB/s transfer rate.

On computer this serial console is accessible via /dev/ttyACM0 device.
