KVM: arm64: Shave a few bytes from the EL2 idmap code
Our idmap is becoming too big, to the point where it doesn't fit in
a 4kB page anymore.
There are some low-hanging fruits though, such as the el2_init_state
horror that is expanded 3 times in the kernel. Let's at least limit
ourselves to two copies, which makes the kernel link again.
At some point, we'll have to have a better way of doing this.
