target/arm: add RAZ/WI handling for DBGDTR[TX|RX]

The commit b3aa2f2128 (target/arm: provide stubs for more external
debug registers) was added to handle HyperV's unconditional usage of
Debug Communications Channel. It turns out that Linux will similarly
break if you enable CONFIG_HVC_DCC "ARM JTAG DCC console".

Extend the registers we RAZ/WI set to avoid this.
