arm64: armv8_deprecated: fold ops into insn_emulation

commit b4453cc8 upstream.

The code for emulating deprecated instructions has two related
structures: struct insn_emulation_ops and struct insn_emulation, where
each struct insn_emulation_ops is associated 1-1 with a struct
insn_emulation.

It would be simpler to combine the two into a single structure, removing
the need for (unconditional) dynamic allocation at boot time, and
simplifying some runtime pointer chasing.

This patch merges the two structures together.

There should be no functional change as a result of this patch.
