[PATCH 09/20] accel/tcg: Restrict 'icount_align_option' global to TCG

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Since commit 740b1759734 ("cpu-timers, icount: new modules")
we don't need to expose icount_align_option to all the
system code, we can restrict it to TCG. Since it is used as
a boolean, declare it as 'bool' type.
