dm: core: Add dev_get_addr_ptr() to return a pointer to the reg address
On some platforms (e.g. x86), the return value of dev_get_addr() can't be assigned to a pointer type variable directly. As there might be a difference between the size of fdt_addr_t and the pointer type. On x86 for example, "fdt_addr_t" is 64bit but "void *" only 32bit. So assigning the register base directly in dev_get_addr() results in this compilation warning: warning: cast to pointer from integer of different size This patch introduces the new function dev_get_addr_ptr() that returns a pointer to the 'reg' address that can be used by drivers in this case.
