This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.
This reduces the attack surface on such systems and should also save
some memory.

This activates "Emulate Privileged Access Never using TTBR0_EL1
switching" on ARM64.
This should prevent the kernel from reading code from user space in
kernel context.

To make it easier to support multiple kernel versions in parallel also
copy the sub target specific kernel configurations into kernel specific
files.
