[SPARC32]: Remove superfluous 'kernel_end' alignment on sun4c.
In sun4c_init_clean_mmu(), aligning 'kernel_end' using SUN4C_REAL_PGDIR_ALIGN() is unnecessary since the caller does this already. In sun4c_paging_init(), 4 page sizes of "fluff" were added to the address of &end. This was necessary a long time ago when sparc32 would allocate some early data structures by carving out memory chunks after &end but that no longer occurs.
