[PATCH v8 15/24] core: read: add dev_read_addr_index_ptr function

[Johan Jonker]

Add dev_read_addr_index_ptr function with the
same functionality as dev_read_addr_index,
but instead a return pointer is given.
Use map_sysmem() function as cast for the return.
Make same fix for dev_read_addr_ptr() function.
