[PATCH] libata-hp-prep: implement followup softreset handling
In some cases, hardreset must be followed by SRST.
* some controllers can't classify with hardreset
* some controllers can't wait for !BSY after hardreset (LLDD should
explicitly request followup softreset by returning -EAGAIN)
* (later) PM needs SRST w/ PMP==15 to operate after hardreset
To handle above cases, this patch implements follow-up softreset.
After a hardreset, ata_eh_reset() checks whether any of above
conditions are met and do a follow-up softreset if necessary.
