libata: move link onlineness check out of softreset methods
Currently, SATA softresets should do link onlineness check before actually performing SRST protocol but it doesn't really belong to softreset. This patch moves onlineness check in softreset to ata_eh_reset() and ata_eh_followup_srst_needed() to clean up code and help future sata_mv changes which need clear separation between SCR and TF accesses. sata_fsl is peculiar in that its softreset really isn't softreset but combination of hardreset and softreset. This patch adds dummy private ->prereset to keep the current behavior but the driver really should implement separate hard and soft resets and return -EAGAIN from hardreset if it should be follwed by softreset.
