serial: sh-sci: Move SCBRR calculation algo in to platform data. 

This permits each port to select its own SCBRR calculation algorithm,

only 5 different variations that all parts fall under.

/*
* Values for the BitRate Register (SCBRR)
*
* The values are actually divisors for a frequency which can
* be internal to the SH3 (14.7456MHz) or derived from an external
* clock source. This driver assumes the internal clock is used;
* to support using an external clock source, config options or
* possibly command-line options would need to be added.
*
* Also, to support speeds below 2400 (why?) the lower 2 bits of
* the SCSMR register would also need to be set to non-zero values.
*
* -- Greg Banks 27Feb2000
*
* Answer: The SCBRR register is only eight bits, and the value in
* it gets larger with lower baud rates. At around 2400 (depending on
* the peripherial module clock) you run out of bits. However the
* lower two bits of SCSMR allow the module clock to be divided down,
* scaling the value which is needed in SCBRR.
*
* -- Stuart Menefy - 23 May 2000
*
* I meant, why would anyone bother with bitrates below 2400.
*
* -- Greg Banks - 7Jul2000

* You "speedist"! How will I use my 110bps ASR-33 teletype with paper
* tape reader as a console!
