regulator: ab8500: Add missing enable_time settings 

Base on the data provide by Bengt Jönsson, add below enable_time settings:

Worst case enable time from data sheet:
Vana: enable time = 140 us
Vaux1/2: enable time = 200 us
Vaux3: enable time = 450 us
Vintcore: enable time = 750 us
Vamic1/2: enable time = 500 us
Vdmic: enable time = 420 us
VTVout: enable time = 500 us
Vaudio: enable time = 140 us
Vusb: enable time = 150 us
