[PATCH v2] Input: Add support for PDP Xbox One controllers

[Mark Furneaux <mark@furneaux.ca> (by way of Mark Furneaux <mark@furneaux.ca>)]

Input: Add support for PDP Xbox One controllers

Adds support for the current lineup of Xbox One controllers from PDP
(Performance Designed Products). These controllers are very picky with
their initialization sequence and require an additional 2 packets before
they send any input reports.

Signed-off-by: Mark Furneaux <mark@furneaux.ca>

Changes in v2:

- Zeroed the sequence numbers and removed the redundant quirk entry.
- Corrected mangled formatting from my email client.
