[PATCH] drm/ssd130x: Make ssd130x_remove() return void

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

This function returns zero unconditionally, so there isn't any benefit
of returning a value. Make it return void to be able to see at a glance
that the return value of ssd130x_i2c_remove() is always zero.

This patch is a preparation for making i2c remove callbacks return void.
