accel/tcg: fix missing includes for TARGET_HAS_PRECISE_SMC

accel/tcg: fix missing includes for TARGET_HAS_PRECISE_SMC

We prepare to remove cpu.h from cpu-all.h, which will transitively
remove it from accel/tcg/tb-internal.h, and thus from most of tcg
compilation units.

Note: this was caught by a test regression for s390x-softmmu.
