powerpc/booke: Disable STRICT_KERNEL_RWX, DEBUG_PAGEALLOC and KFENCE

mainline inclusion
from mainline-v5.16-rc1
commit 68b44f94
category: bugfix
bugzilla: 185780 https://gitee.com/openeuler/kernel/issues/I4EUY7

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=68b44f94d6370e2c6c790fedd28e637fa9964a93



-------------------------------------------------

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: 88df6e90 ("[POWERPC] DEBUG_PAGEALLOC for 32-bit")
Fixes: 95902e6c ("powerpc/mm: Implement STRICT_KERNEL_RWX on PPC32")
Fixes: 90cbac0e ("powerpc: Enable KFENCE for PPC32")
