SCIFA ports on sh7723 and sh7724 seem to use a sampling rate of half the
value specified in the datasheet. This is currently handled by a custom
baud rate calculation algorithm. The algorithm ID will be removed from
platform data, set the sampling rate directly instead.

Computing the baud rate register value requires knowledge of the
hardware sampling rate. This information is currently encoded in a baud
rate calculation algorithm ID passed through platform data. However, it
can be derived from the port type directly in most cases.

Compute the sampling rate internally in the driver if the baud rate
calculation algorithm ID isn't specified, and allow platforms to
override the sampling rate through platform data in special cases (this
is only required for SCIFA ports on sh7723 and sh7724, the reason needs
to be investigated).
