hid: bpf: Fix grammar

* spelling fix: XBox -> Xbox, lowercase 'b' as per Microsoft branding
* rephrase: paddle -> paddles, the controller itself has more than one paddle
* rephrase: replace usage of "those" in favor of explicitly making reference
  to the paddles
* grammatical fix: report -> reports, use present tense verb.
* spelling fix: interpret
* consistency: capitalize the first word in bullet points
