[ARM] 4982/1: [AT91] Drop old-style UART initialization (Part 1)
All the SAM9 boards supported by mainline and the AT91 patches have been converted to the new-style UART initialization. Therefore drop support for the old at91_init_serial() interface for SAM9. at91_uarts[] array can also be marked as __initdata. The warning that no serial-console is defined moved from at91_set_serial_console() to at91_add_device_serial() since the whole point is the board-specific file is not calling at91_set_serial_console().
