 Modified Files:
 	src/sys/dev/ic: ahcisata_core.c
 
 Log Message:
 during SRST (softreset), make a short delay between the RST set and
 clear; SATA specifies minimum 5 usec for the toggle period, and
 some controllers (seems usually on AMD motherboards) actually require it
 
 this fixes the 'clearing WDCTL_RST failed' error in PR kern/53307
 and PR kern/53524
 
 confirmed working on a ASUS Prime A320M-K mainboard by me, and by Patrick
 Welche on another Ryzen system
