[PATCH 5.4 40/80] net: ieee802154: ca8210: Fix lifs/sifs periods

[Greg Kroah-Hartman]

From: Miquel Raynal <miquel.raynal@xxxxxxxxxxx>

commit bdc120a2bcd834e571ce4115aaddf71ab34495de 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.
