hmt(4): Do not require input report HID usages to be a member of TLC

Some touchpads places button usages (in HID report descriptor) in to
the 2-nd level collection rather than in to the top level one. That
confuses current code. Remove collection level check in HID report
descriptor parser to fix device detection.

hmt(4): Add support for serial packet reporting mode

In Serial mode, each packet contains information that describes a
single physical contact point. Multiple contacts are streamed
serially. In this mode, devices report all contact information in a
series of packets. The device sends a separate packet for each
concurrent contact.

Serial packet reporting mode is used by post-2014 eGalax touchscreens.
