target/xtensa: Replace legacy cpu_physical_memory_[un]map() calls

Commit b7ecba0f6f6 ("docs/devel/loads-stores.rst: Document our
various load and store APIs") mentioned cpu_physical_memory_*()
methods are legacy, the replacement being address_space_*().

Replace the *_map() / *_unmap() methods in the SIMCALL helper,
using the vCPU default address space. No behavioral change expected.
