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

Browse Source 
This permits each port to select its own SCBRR calculation algorithm,
rather than having it all ifdef'ed in the header. There are presently
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!
