[PATCH v8 17/24] drivers: use dev_read_addr_index_ptr when cast to pointer

[Johan Jonker <jbx6244@gmail.com>]

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
dev_read_addr_index_ptr instead of the dev_read_addr_index function
in the various files in the drivers directory that cast to a pointer.
As we are there also streamline the error response to -EINVAL on return.

Changed V6:
  use -EINVAL on return
  drop cast
