init/Kconfig: move more items into the EXPERT menu

Browse Source 
KCMP, RSEQ, CACHESTAT_SYSCALL, and PC104 depend on EXPERT but not shown in
the EXPERT menu.  Move some lines around so that they are displayed in the
EXPERT menu.

Drop one useless comment.

Change "enabled" to "enable" for DEBUG_RSEQ.
