Print symbol names in comments for LDS/STS disassembly.

This patch adds default data address space origin (0x800000) to the symbol addresses.
when disassemble lds/sts instructions. So that symbol names shall be printed in comments
for lds/sts instructions disassemble.

	* avr-dis.c (avr_operand): Add default data address space origin (0x800000) to the
	address and set as symbol address for LDS/ STS immediate operands.
