A follow-up to commit842fb5de42
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer") and commit320a1938b6
("drivers: use devfdt_get_addr_index_ptr when cast to pointer"). In addition to using the *_ptr variants of these functions where the address is cast to a pointer, this also changes devfdt_get_addr_*() to dev_read_addr_*() in a few places. Some variable and field types are changed from fdt_addr_t or phys_addr_t to void* where the cast was happening later. This patch fixes a number of compile warnings when building a 32bit U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error handling where the return value of dev_read_addr() etc. was checked for NULL instead of FDT_ADDR_T_NONE.
