net: ipa: update comments
This patch just updates comments throughout the IPA code.
Transaction state is now tracked using indexes into an array rather
than linked lists, and a few comments refer to the "old way" of
doing things. The description of how transactions are used was
changed to refer to "operations" rather than "commands", to
(hopefully) remove a possible ambiguity.
IPA register offsets and fields are now handled differently as well,
and the register documentation is updated to better describe the
code.
A few minor updates to comments were made (e.g., adding a missing
word, fixing a typo or punctuation, etc.).
Finally, the local macro atomic_dec_not_zero() is no longer used, so
it is deleted.
