Add support for updating the idbloader and u-boot images through the UEFI capsule update functionality. Enable the modules required for supporting the functionality.
The implementation is for the updatable images placed on a GPT partitioned storage device. With the GPT partition devices, the partition information can be obtained at runtime, and hence the dfu_alt_info variable needed for the updates is being populated at runtime.
This requires the partitions containing the idbloader and u-boot images to be created with the PartitionTypeGUID values set to the corresponding image type GUID values defined in the platform's config header(ROCKPI_4{B,C}_IDBLOADER_IMAGE_GUID and ROCKPI_4{B,C}_UBOOT_IMAGE_GUID).
I think it would be useful to break this patch down into more than one patch. At least the core changes to evb_rk3399/evb-rk3399.c and the board specific changes. Also given these changes arre likely of interest to other boards should they go to somewhere more central than evb_rk3399/evb-rk3399.c to enable less code duplication across rk3399 or even rockchip devices as a whole?
