net: ieee802154: mcr20a: Fix lifs/sifs periods

BugLink: https://bugs.launchpad.net/bugs/1960516
commit d753c4004820a888ec007dd88b271fa9c3172c5c 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 phy->symbol_duration in order to get these
values in microseconds.
