[PULL 03/11] hw/arm/fsl-imx6ul: Instantiate unimplemented pwm and can devices

[Peter Maydell <peter.maydell@linaro.org>]

From: Guenter Roeck <linux@roeck-us.net>

Recent Linux kernels (post v4.20) crash due to accesses to flexcan
and pwm controllers. Instantiate as unimplemented devices to work
around the problem.
