hw/riscv: Mark RISC-V specific peripherals as little-endian
These devices are only used by the RISC-V targets, which are
only built as little-endian. Therefore the DEVICE_NATIVE_ENDIAN
definition expand to DEVICE_LITTLE_ENDIAN (besides, the
DEVICE_BIG_ENDIAN case isn't tested). Simplify directly
using DEVICE_LITTLE_ENDIAN.
