CVE: NA

----------------------------------------------------------------

The ahci spec mentions that PhyRdy Change Interrupt and Link Power
Management (LPM) do not coexist. However, before enabling LPM,
the driver did not check whether the host supports LPM,
but directly disabled PhyRdy Change Interrupt. Increase the
judgment on the actual support of LPM, and disable PhyRdy Change
Interrupt only when it is supported.
