[COMMON] media: smfc: use s/w timer if HWFC is enabled

If HWFC is enabled, the internal timer in the H/W is not available
because when the H/W finishes depends on the outside of SMFC itself.
Instead of the internal timer, S/W timer is used for the case of HWFC.
S/W timer is expired if the H/W is not completed in a second that is
quite huge amount of time.
