goldfish_rtc_of_to_plat() currently returns success even when
dev_read_addr() fails to find a valid address. This leaves plat->reg
unset (or 0) and defers the failure to probe().
Return -EINVAL immediately when the address is FDT_ADDR_T_NONE so the
failure is reported at the of_to_plat stage where it belongs. This
aligns the driver with the recent fix introduced in the goldfish
serial driver by Naveen Kumar Chaudhary. [1]
