AHCI - Fix PM probing issues, wait 10 seconds on physical port insertion
* The spec is not completely clear on the point but CCB[1] *MUST* be used
as the second CCB in a softreset sequence. If it isn't, the wrong
signature may be loaded into the signature register.
* Wait 10 seconds on insertion of a physical port (we already wait 10 seconds
on the insertion of a target behind a PM).
* Do not cycle the PHY when doing a hard reset, it seems to create
detection problems.
