[PULL 20/59] physmem: Move TCG IOTLB methods around

[Richard Henderson]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

The next commit will restrict TCG specific code in physmem.c
using some #ifdef'ry. In order to keep it simple, move
iotlb_to_section() and memory_region_section_get_iotlb()
around close together.
