hw/ppc: Take QEMU lock when calling ppc_dcr_read/write()
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.
