clear_pages() is never used expect by clear_page, and PPC32 is the only architecture (still) having this function. Neither PPC64 nor any other architecture has it. This patch removes clear_pages() and moves clear_page() function inline (same as PPC64) as it only is a few isns Signed-off-by:

[PATCH] powerpc/83xx: disable IDE subsystem in mpc834x_itx_defconfig
