target/xtensa: Use probe_access for itlb_hit_test 

We don't actually need the result of the read, only to probe that the
memory mapping exists.  This is exactly what probe_access does.

This is also the only user of any cpu_ld*_code_ra function.
Removing this allows the interface to be removed shortly.
