sata_nv: ck804 has borked hardreset too 



While playing with nvraid, I found out that rmmoding and insmoding
often trigger hardreset failure on the first port (the second one was
always okay).  Seriously, how diverse can you get with hardreset
behaviors?  Anyways, make ck804 use noclassify variant too.

/* CK804 finally gets hardreset right */

/* For initial probing after boot and hot plugging, hardreset mostly

 * in somewhat undeterministic way.  Use noclassify hardreset.
