Subject: [PATCH] git commit --signoff -m "mtd: cadence: Fix cast to pointer from integer of different size warning

Use a cast to uintptr_t and next to a pointer
In the final assignment the same casting in place
memory_pointer = (uintptr_t)mem_ptr;
Fix warning: cast to pointer from integer of different size
