[PATCH v3 07/33] serial: sh-sci: Improve readability of sampling rate configuration

[Geert Uytterhoeven <geert+renesas@glider.be>]

Reorder sampling_rate assignment for consistency in all cases of the
switch statement.
Avoid using the ternary conditional operator to make it more clear that
the value is overridden by platform data.

v3:
