drivers: use devfdt_get_addr_ptr when cast to pointer

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
devfdt_get_addr_ptr instead of the devfdt_get_addr function in
the various files in the drivers directory that cast to a pointer.
