hal: select IPIPE_WANT_ACTIVE_MM when needed
Starting with the I-pipe core for Linux 3.5, Xenomai should select the
CONFIG_IPIPE_WANT_ACTIVE_MM symbol when it is not possible to rely on
current->active_mm to get the current mm. This means:
- when unlocked context switches are enabled on powerpc and sh
- always on arm.
