Ard Biesheuvel 1fb805b1eb MdeModulePkg/AtaAtapiPassThru: relax PHY detect timeout
The SATA spec mandates that link detection by the PHY completes within
10 ms after receiving a reset signal. However, there is no obligation
to uphold this requirement at the driver end as strictly as we do, and
as it turns out, some combinations of host and device (e.g., Samsung
850 EVO connected to a LeMaker Cello) are only borderline compliant,
which means the device is not detected reliably.

So let's allow for a bit of margin, and increase the PHY detect timeout
value to 15 ms.
