The DRAM configuration GPIO straps must be accessible in all boot phases because the GPIOs are sampled both in U-Boot SPL as well as early on in U-Boot proper. The already present bootph-pre-ram DT property made the GPIO controllers available in SPL, but not early on in U-Boot proper, which made gpio_request_list_by_name_nodev() in board dmo_get_memcfg() fail. Add missing bootph-all DT property to all GPIO controllers which are referenced in dmo,ram-coding-gpios DT property to make those GPIO controllers available early in U-Boot proper as well.
