====================
net: ipa: IPA register cleanup

This series consists of cleanup patches, almost entirely related to
the definitions for IPA registers.  Some comments are updated or
added to provide better information about defined IPA registers.
Other cleanups ensure symbol names and their assigned values are
defined consistently.  Some essentially duplicate definitions get
consolidated for simplicity.  In a few cases some minor bugs
(missing definitions) are fixed.  With these changes, all IPA
register offsets and associated field masks should be correct for
IPA versions 3.5.1, 4.0, 4.1, and 4.2.
