This removes complaints about the gadget stack which are generated by
the currrent "sparse":  it doesn't like the fact that zero is the null

Renesas m66592-udc driver.  Updates include:

 - Fix some locking bugs; and add a few sparse annotations
 - Don't #define __iomem !
 - Lots of whitespace fixes (most of the patch by volume)
 - Some #include file trimmage
 - Other checkpatch.pl and sparse updates
 - Alphabetized and slightly-more-informative Kconfig
 - Don't use the ID which was assigned to the amd5536udc driver.
 - Remove pointless suspend/resume methods updating obsolete field.
 - Some section fixups
 - Fix some leak bugs
 - Fix byteswapping
