USB: quirks: add NO_LPM for the Samsung T5 EVO Portable SSD
The Samsung T5 EVO Portable SSD (04e8:6200) exhibit two forms of
link instability when USB Link Power Management is enabled:
1. The units fail to initialize properly on first detection,
resulting in a lockup in the drive where it must be power cycled
or the kernel will not recognize the presence of the device.
2. If used for sustained operations (small amounts of continuous
data are transferred to the unit) then the unit will "hiccup"
after roughly 8 hours of use and will disconnect and reconnect.
This has a certain probability of triggering the first issue,
but also causes mount points to become invalid since the device
gets issued a new letter.
