qemu-arm64: Enable POSITION_INDEPENDENT

Now that PIE works when U-Boot is started from ROM, let's enable
CONFIG_POSITION_INDEPENDENT, which allows to load U-Boot also via
ARM Trusted-Firmware's fip.bin to DRAM, without tweaking the
configuration.

To get a writable initial stack, we need to keep the fixed initial
stack pointer, which points to DRAM in our case.
