The ppc_dcr_read() and ppc_dcr_write() functions call into callbacks in device code, so we need to hold the QEMU iothread lock while calling them. This is the case already for the callsites in kvmppc_handle_dcr_read/write(), but we must also take the lock when calling the helpers from TCG. This fixes a bug where attempting to initialise the PPC405EP SDRAM will cause an assertion when sdram_map_bcr() attempts to remap memory regions.
