realtek: image: pin FLASH_ADDR per device

FLASH_ADDR is referenced inside Build/rt-loader-standalone but is not
listed in DEVICE_VARS, so include/image.mk's Device/Export does not
emit a per-target FLASH_ADDR := <value> assignment for the standalone
loader recipe. At recipe expansion time $(FLASH_ADDR) therefore
resolves to whatever value the last device in TARGET_DEVICES set
globally, which is not necessarily the value belonging to the loader
being built.

This currently happens to produce correct binaries only because every
device that sets FLASH_ADDR within a given subtarget shares the same
value, so the leaked global matches by coincidence.

Add FLASH_ADDR to DEVICE_VARS so each loader recipe captures its own
device's address.
