serial: sc16is7xx: reorder code to remove prototype declarations

Move/reorder some functions to remove sc16is7xx_ier_set() and
sc16is7xx_stop_tx() prototypes declarations.

No functional change.

sc16is7xx_ier_set() was introduced in
commit cc4c1d05eb10 ("sc16is7xx: Properly resume TX after stop").
