powerpc/booke: Disable STRICT_KERNEL_RWX, DEBUG_PAGEALLOC and KFENCE
fsl_booke and 44x are not able to map kernel linear memory with pages, so they can't support DEBUG_PAGEALLOC and KFENCE, and STRICT_KERNEL_RWX is also a problem for now. Enable those only on book3s (both 32 and 64 except KFENCE), 8xx and 40x. Fixes:88df6e90fa
("[POWERPC] DEBUG_PAGEALLOC for 32-bit") Fixes:95902e6c88
("powerpc/mm: Implement STRICT_KERNEL_RWX on PPC32") Fixes:90cbac0e99
