drivers: use dev_read_addr_ptr when cast to pointer

2023-05-06T09:28:18+00:00

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_ptr instead of the dev_read_addr 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.
