Add two new configurations (qemu-riscv{32,64}_spl_defconfig) with SPL enabled for RISC-V QEMU. QEMU does not require SPL to run U-Boot. The configurations are meant to help the development of SPL on RISC-V.
The configurations enable RAM as the only SPL boot device. Images must be loaded at address 0x80200000. In the default boot flow, U-Boot SPL starts in machine mode, loads the OpenSBI FW_DYNAMIC firmware and U-Boot proper from the supplied FIT image, and starts OpenSBI. U-Boot proper is then started in supervisor mode by OpenSBI.
