serial: sh-sci: support lower baud rate Support prescaler 1/16 and 1/64, in addition to current 1 and 1/4. Supporting below 2400bps was dropped long time ago in mainline. Since then, setting lower rate has been resulting in erroneous register value, without indicating any errors through API. This patch adds more prescaler to support lower rates again. This still doesn't check range, but we won't hit the case because even 50bps at 48MHz clock is now supported.
