Enabling Octal DTR mode in multi-die package parts requires reister setup for each die. That can be done by simple for-loop. write_enable() takes effect to all die at once so we can call it before the loop. Besides we can replace spi_mem_exec_op() calls with spansion_read/write_any_reg(). And finally, we must mask CFR2V[7:4] when changing dummy cycles, as CFR2V[7] indicates current addressing mode and that should be 1 (4-byte address mode) for multi-die package parts.
