The normal order is: vendor,soc-block

Do you expect a lot of chips with the exact same version of the IP? If 
not drop. Future chips can always use toshiba,pwm-tmpv7708 as a 
fallback.

Drop. No need to describe common properties.

Drop.

Currently it still supports only one IP. Therefore, "toshiba, pwm-visconti"
is enough for now. I will drop enum line..
