Kai-Heng Feng 9947d6a09c nvme: relax APST default max latency to 100ms 
Christoph Hellwig suggests we should to make APST work out of the box.
Hence relax the the default max latency to make them able to enter
deepest power state on default.

Here are id-ctrl excerpts from two high latency NVMes:

ssvid   : 0x1b4b
