socfpga: Allow setting partition xloader boots from for mmc
The xloader boots the 2nd stage barebox from socfpga_barebox_part when using NOR. But when using MMC it boots from a hardcoded "disk0.1". Add the mmc device name to the partition description and use it for mmc booting. Add an extern declaration of socfpga_barebox_part to the socfpga header so that a board can change it to use a different partition. Initialize socfpga_barebox_part to the default value instead of NULL to avoid the NULL check later.
