[ 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.
