[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().
