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.
