nb1010: Add support for NB-2020-U fingerprint reader

Browse source 
Add USB PID 0x2020 (NB-2020-U) to the nb1010 driver's id_table.

The NB-2020-U is an embedded variant of the NB-1010-U using an
identical sensor die (confirmed by independent teardown reports from
System Plus Consulting/Yole Group). USB endpoint layout, command
protocol and image format are identical between both devices.

Tested on a Fujitsu notebook with integrated NB-2020-U reader
(USB ID 298d:2020): device enumeration, finger detection polling
and image capture all work correctly with the existing nb1010
driver code.
