avr.h (LEGITIMIZE_RELOAD_ADDRESS): Pass address of X instead of X to avr_legitimize_reload_address.

	* config/avr/avr.h (LEGITIMIZE_RELOAD_ADDRESS): Pass address of X
	instead of X to avr_legitimize_reload_address.
	* config/avr/avr-protos.h (avr_legitimize_reload_address): Change
	first argument's type from rtx to rtx*.
	* config/avr/avr.c (avr_legitimize_reload_address): Ditto.
	Pass PX to push_reload instead of &X.  Change log messages for
	better distinction.
