AVR ELPMX instruction (and some others) use three registers to
form long 24-bit address from RAMPZ and two 8-bit registers.
RAMPZ stores shifted 8 bits like ff0000 to simplify address calculation.
This patch fixes full address calculation in function gen_get_addr
by changing the mess in offsets of deposit tcg instructions.
