bits: add comments and newlines to #if, #else and #endif directives
[ Upstream commit 31299a5e0211241171b2222c5633aad4763bf700 ]
This is a preparation for the upcoming GENMASK_U*() and BIT_U*()
changes. After introducing those new macros, there will be a lot of
scrolling between the #if, #else and #endif.
Add a comment to the #else and #endif preprocessor macros to help keep
track of which context we are in. Also, add new lines to better
visually separate the non-asm and asm sections.
