[SCSI] aci94xx: implement link rate setting This patch implements the ability to set the minimum and maximum linkrates for both libsas (for expanders) and aic94xx (for the host phys). It also tidies up the setting of the hardware min and max to make sure they're updated when the expander emits a change broadcast. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
