 ramp delay

Hi Krzysztof

Apologies for the delay. I was on vacation during the early part of
this month and
got busy with some other stuff later and this mail fell through the cracks.

I checked the datasheet available with me and according to it

buck 1 and 6 share the ramp register 0x11 (RAMP2) (bit 4 and 5) and buck 3 uses
bit 4 and 5 of register 0x10 (RAMP1).
