Tejun Heo f659f0e448 libata-sff: handle controllers w/o ctl register
SFF incorrectly assumed that ctl register is available for all
controllers while some old SFF controllers don't have ctl register.
Make SFF handle controllers w/o ctl register by conditionalizing ctl
register access and softreset method.
