fpu/softfloat.c: Return correctly signed values from uint64_to_float32
The uint64_to_float32() conversion function was incorrectly always returning numbers with the sign bit set (ie negative numbers). Correct this so we return positive numbers instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
