From: AKASHI Takahiro takahiro.akashi@linaro.org
In efi world, there is no obvious "mkdir" interface, instead, Open() with EFI_FILE_MODE_CREATE in mode parameter and EFI_FILE_DIRECTORY in attributes parameter creates a directory.
In this patch, efi_file_open() is extended so as to accept such a combination of parameters and call u-boot's mkdir interface for expected action.
