p54: more definitions form lmac_longbow.h and pda.h
This patch ports more useful features to p54 - PDR definitions for the synth chips & regulatory domain. - honour IEEE80211_TX_CTL_ASSIGN_SEQ flag, if it's set. - adds some lost mutex_lock & mutex_unlock. - replace two more "magic values" that sneaked past.
