[PATCH 04/12] hw/riscv: Move sifive_gpio model to hw/gpio

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

This is an effort to clean up the hw/riscv directory. Ideally it
should only contain the RISC-V SoC / machine codes plus generic
codes. Let's move sifive_gpio model to hw/gpio directory.

Note this also removes the trace-events in the hw/riscv directory,
since gpio is the only supported trace target in that directory.
