Sorry, forgot to mention: I can't flip the default behaviour to leave
virtualization support off only for the TK1. That's a generic default.

So we can either leave out the last patch for now and wait until the
cpu-idle fix is upstream or tell the people picking upstream u-boot to
turn either virt support in u-boot on or CPU_IDLE in the kernel off
(just tell me where to put such a note).
