[PATCH 25/26] tests/functional/riscv64: Add Icicle Kit firmware boot test

[Bin Meng <bin.meng@processmission.com>]

Add functional coverage using prebuilt HSS and SD card images.

Boot HSS and U-Boot with five harts and 2 GiB of RAM. Connect
the test console to MMUART1 and let U-Boot start Linux.

The complete boot exercises the SDHCI controller in the DMA modes
used at each stage. HSS uses Version 4 64-bit SDMA to load U-Boot.
U-Boot uses ADMA2-64 to read the boot script and the large FIT
image. Linux then selects 64-bit ADMA for SD card and rootfs I/O.

Check the machine identity, kernel ADMA initialization, root
filesystem mount, and login prompt.
