Subject: [PATCH v3 7/7] c-sky: Remove now superfluous sentinel element from
 ctl_talbe array

From: Joel Granados <j.granados@...sung.com>

This commit comes at the tail end of a greater effort to remove the
empty elements at the end of the ctl_table arrays (sentinels) which
will reduce the overall build time size of the kernel and run time
memory bloat by ~64 bytes per sentinel (further information Link :
https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/)

Remove sentinel from alignment_tbl ctl_table array. This removal is safe
because register_sysctl_init implicitly uses ARRAY_SIZE() in addition to
checking for the sentinel.
