net: ieee802154: ca8210: Fix lifs/sifs periods

Browse source 
commit bdc120a2bc upstream.

These periods are expressed in time units (microseconds) while 40 and 12
are the number of symbol durations these periods will last. We need to
multiply them both with the symbol_duration in order to get these
values in microseconds.
