This adds QEMU RISC-V 'virt' board target support, with the hope of helping people easily test U-Boot on RISC-V.
The QEMU virt machine models a generic RISC-V virtual machine with support for the VirtIO standard networking and block storage devices. It has CLINT, PLIC, 16550A UART devices in addition to VirtIO and it also uses device-tree to pass configuration information to guest software. It implements RISC-V privileged architecture spec v1.10.
Both 32-bit and 64-bit builds are supported. Support is pretty much preliminary, only booting to U-Boot shell with the UART driver on a single core. Booting Linux is not supported yet.

Out of curiosity, what is BOARD_SPECIFIC_OPTIONS used for? I see that other boards have included it as well, but I don't see it actually used anywhere.
Thanks, Lukas
