[PATCH 05/15] ARM: i.MX: xload-gpmi: Fix compiler warning

[Sascha Hauer]

'pdesc' is a pointer casted to a 32bit value. This rightfully issues a
compiler warning when being compiled with a 64bit toolchain. This code
is compiled on 64bit systems, but the hardware won't be used there.
Just silence the warning by casting the pointer to unsigned long.
