[RFC PATCH v5 0/9] target/arm: Allow CONFIG_TCG=n builds

[Fabiano Rosas]

This series makes the necessary changes to allow the use of
--disable-tcg for arm.

Based on "target/arm: CONFIG_TCG=n part 1":

Since v4:

- Used "max" as the default CPU for KVM-only builds. This allows me to
  drop all the clunky qtest changes and it keeps disabling TCG
  separate from changing cpu defaults.

  I'm neutral towards removing the defaults for arm. We can do that in a
  separate series. It would be nice to make the TCG default equal to the
  non-TCG one. Otherwise we're bound to get reports that "this command
  line used to work" if users switch from: 'CONFIG_TCG=n -accel kvm' to
  'CONFIG_TCG=y -accel kvm' (the latter would try to use the cortex-a15
  as default).

- Move the ifdef around valid_cpus into the patches that move the
  respective cpus. Patches 1 & 2.
