arm64: entry: Allow handling of undefined instructions from EL1
[ Upstream commit 0bf0f444b2c49241b2b39aa3cf210d7c95ef6c34 ]
Rather than panic() when taking an undefined instruction exception from
EL1, allow a hook to be registered in case we want to emulate the
instruction, like we will for the SSBS PSTATE manipulation instructions.
