net: ax88796: avoid 64 bit arithmetic

When building ax88796 on an ARM platform with 64-bit resource_size_t, we currently get drivers/net/ethernet/8390/ax88796.c:875: undefined reference to `__aeabi_uldivmod' because we do a division on the length of the MMIO resource. Since we know that this resource is very short, using an "unsigned long" instead of "resource_size_t" is entirely sufficient, and avoids this link-time error.
