[PATCH] linker_lists: Update the alignment using CONFIG_LINKER_LIST_ALIGN

[1425075683 at qq.com]

From: Liya Huang <1425075683 at qq.com>

This patch updates the alignment of linker lists to use the
CONFIG_LINKER_LIST_ALIGN macro instead of a hardcoded value.
This ensures that the alignment is consistent with the configuration.
Replace __attribute__((unused)) with __maybe_unused and
__always_unused to eliminate the warning of checkpatch.pl.
