misc: ad525x_dpot: Make ad_dpot_remove() return void

Browse Source 
Up to now ad_dpot_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 i2c and spi remove callbacks is ignored anyway.
