arm64: Remove the E2H check from has_hyp

[andrew]

Summary

This was added to not use the physical timer when E2H was set. As we
now use the correct timer in this case we can remove this extra check.

@kevans This should be a partial revert of rGd2ae03bae2add82124973876dec95eb126ff34c8. Can you test to make sure I didn't break anything before I commit?

Ack- I'll try to rebase my branch and test this in the next day or two.

You can get it from https://github.com/zxombie/freebsd/commit/9eebbc0464314b7515f59a7af8fbe3dda20fb94f, and https://github.com/zxombie/freebsd/commit/7ff0b43dbdcbbd31b3ff471adac1454bd15a516b to enable VHE when possible.

Boots fine; I was going to try and at least test-load vmm, but I can't easily get vmm.ko onto this setup at the moment and options VMM seems to be pretty broken at the moment on arm64.
