Remove blackfin specific implementation of the generic serial API when
early print macro is defined.
In BFIN_BOOT_BYPASS mode, don't call generic serial_puts, because
early print in bypass mode is running before code binary is relocated
to the link address.

Calculate the early uart clock from the system clock registers set by
the bootrom other than the predefine uboot clock macros.
Split the early baudrate setting function and the normal baudrate
setting one.

Rename the serial_register_bfin_uart() to bfin_initialize_serial()
to be consistent with the rest of the naming. Next, remove it's
prototype from serial.h and properly insert it into serial.c as
the rest of the serial initialization functions.

Rename .init() to .start() and .uninit() to .stop() in struct
serial_device. This allows aligning struct serial_device with
closer to struct stdio_dev. The real goal here is to allow
these two structures to converge together and eventually make
one to be a superset of the other.

This allows the Blackfin UART driver to be tested via post.

Since the serial struct declares the sizes for us, no need to hardcode
them in the accessor functions. Let the bfin_{read,write} helpers do
it for us.

The code uses %i to printf a size_t when it should use %zu, otherwise
we get a warning from gcc about it.

This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs.
Ends up adding only ~512bytes per additional UART.

There's no need for these saved buffers to be global symbols, or in
the data section. So mark them static to move them into the bss.

It can be optimised out by the compiler otherwise resulting
in obscure errors like a board not booting.
This has been documented in README since 2006 when these were
first fixed up for GCC 4.x.
