Martin Åberg a362463fdf boards: qemu_riscv64 use virt machine
Upgrade board specification to use the VirtIO board.

Keeps FPU run-time support disabled since the RISC-V 64-bit FPU
support in kernel appears to be non-functional.

Andrew Boie a9670ab5cf boards: centralize QEMU icount management
Instead of endlessly repeating the same command line args,
centralize this and tune the shift value on a per-board
basis.

Wentong Wu 49bf0ff1ff boards: qemu_riscv64: enable icount mode
Enable icount mode for qemu_riscv64 platform, The icount shift value

Nicolas Pitre 7f74825958 riscv: add a qemu_riscv64 board
This emulates a RISC-V in 64-bit mode on a SiFive FE310 dev board.
Memory is tight so a few tests had to be disabled due to the extra
memory usage compared to qemu_riscv32.
