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
