b1e574d95b Blackfin: serial: convert to bfin_{read,write} helpers
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.

f9aee4b4b6 Blackfin: uart: fix printf warning
The code uses %i to printf a size_t when it should use %zu, otherwise
we get a warning from gcc about it.

635f330fc7 Blackfin: uart: add multiple serial support
This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs.
Ends up adding only ~512bytes per additional UART.

34a6d0b84a Blackfin: uart: move debug buffers into local bss
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.

2956532625 Move DECLARE_GLOBAL_DATA_PTR to file scope
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.
