powerpc/512x: don't compile any platform DIU code if the DIU is not enabled
If the DIU framebuffer driver is not enabled, then there's no point in compiling any platform DIU code, because it will never be used. Most of the platform code was protected in the appropriate #ifdef, but not all. This caused a break in some randconfig builds. This is only a problem on the 512x platforms. The P1022DS and MPC8610HPCD platforms are already correct. This patch reverts commit 12e36309f8774f4ccc769d5e3ff11ef092e524bc ("powerpc: Option FB_FSL_DIU is not really optional for mpc512x") and restores the ability to configure DIU support.
