The DRAM configuration GPIO straps must be accessible in SPL and before
relocation 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-some-ram 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.
