soc/amd/stoneyridge: Fix most checkpatch errors

Correct the majority of reported errors and mark most of the
remaining ones as todo.  (Some of the lines requiring a >80
break are indented too much currently.)  Some of the alignment
in hudson.h still causes checkpatch errors, but this is
intentionally left as-is.

Also make other misc. changes, e.g. consistency in lower-case
for hex values, using defined values, etc.

These changes were confirmed to cause no changes in a Gardenia
build.  No other improvements were made, e.g. changing to helper
functions, or converting functions like __outbyte().
