nimble/phy/nrfx: Add support for extending T_IFS

Browse Source 
This allows to extend T_ifs (inter-frame spacing) by additional
microseconds to improve interoperability with peripherals that
send packets too late (eg 153us). This prolongs reception time by
additional microseconds. Defaults to 2us to improve operations with
devices already on the market.
