[PATCH v3 39/39] accel/tcg: Restrict tcg_exec_[un]realizefn() to TCG

[Richard Henderson <richard.henderson@linaro.org>]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

We don't need to expose these TCG-specific methods to the
whole code base. Register them as AccelClass handlers, they
will be called by the generic accel_cpu_[un]realize() methods.
