imx: bootaux: fix stack and pc assignment on 64-bit platforms
Using ulong is wrong as its size depends on the Host CPU architecture (32-bit vs. 64-bit) although the Cortex-M4 is always 32-bit. Without this patch, the stack and PC are obviously wrong and it generates an abort when used on 64-bit processors such as the i.MX8MQ.
