[RFC PATCH v1 1/4] drivers: use dev_read_addr_index_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 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.

Note:

This is needed for a Rockchip patch serie to pass the test and
must be merged before by Rockchip maintainers:

[PATCH v4 00/11] Fixes for Rockchip NFC driver part 1
