net: mac802154: Convert the symbol duration into nanoseconds
Tdsym is often given in the spec as pretty small numbers in microseconds
and hence was reflected in the code as symbol_duration and was stored as
a u8. Actually, for UWB PHYs, the symbol duration is given in
nanoseconds and are as precise as picoseconds. In order to handle better
these PHYs, change the type of symbol_duration to u32 and store this
value in nanoseconds.
All the users of this variable are updated in a mechanical way.
