[RFC PATCH 03/15] accel/hax: Simplify #ifdef'ry

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

hax_enabled() is called from:

- qemu_init_board() in softmmu/vl.c
- qemu_wait_io_event() in softmmu/cpus.c
- apic_common_realize() in hw/intc/apic_common.c

By converting macros to a function, we can remove the
NEED_CPU_H dependency and build softmmu/cpus.c once
for all targets.
