[PATCH v2 18/20] serial: sc16is7xx: Make sc16is7xx_remove() return void

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

Up to now sc16is7xx_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.

Also the return value of spi remove callbacks is ignored anyway.
