regulators: Moved define for number of regulators in ab8500
The define for number of regulators is moved from ab8500-core to ab8500-regulator so that the regulator driver can be updated independently of ab8500-core. This also changes the platform configuration structure of ab8500-core so that it contains a pointer to the regulator_init_data array plus number of regulators instead of an fixed size array of pointers to regulator_init_data.
