Use config.h as the main source of configuration data. Fixed some boot.c

glitches.

- fw/boot/boot.c, fw/boot/dfu.c: include config.h for platform defines
- fw/common/Makefile.common: add $(F32XBASE)/fw/common to include search
  path
- fw/boot/boot.c: define dummy for uart_init if no debugging is enabled
- fw/boot/boot.c (PLATFORM_EXIT): typo PLAYFORM_EXIT
- fw/boot/boot.c (run_payload): rename BOOT_SETUP to PLATFORM_SETUP
- fw/boot/dfu.c (device_descriptor): use USB_PRODUCT instead of
  USB_PRODUCT_IDBG_DFU
- fw/boot/config.h: removed for now. Might bring it back later as template.
- fw/boot/version.h: moved to fw/common/
- fw/common/Makefile.system: remove serial setup
