usb/misc/usb3503: use regmap write to set nrd and pds
Using regmap update bits the way it was used is wrong as only additional bits
gets set but no bits would be cleared.
The whole register or NRD and PDS are reserved for those two function.
There are no bits which needs to be preserved in the registers so just
writting the new value is all that is needed.
