Replace cpu_physical_memory_rw were possible

Browse source 
Using cpu_physical_memory_read, cpu_physical_memory_write and ldub_phys
improves readability and allows removing some type casts.

lduw_phys and ldl_phys were not used because both require aligned
addresses. Therefore it is not possible to simply replace existing
calls by one of these functions.
