* Description: Write value v to reg and read it back.
*
* Test Type: Feature
*
* Targets: nvgpu_writel_check
*
* Inputs: None
*
* Steps:
* Initialize address space and register io callbacks.
* Call nvgpu_writel_check with value 0. Here read and write value will be
* different as read callback always returns NVGPU_READ_VAL.
* Call nvgpu_writel_check with value NVGPU_READ_VAL. Here read and write value
* will be same as read callback always returns NVGPU_READ_VAL.
*
* Output:
* The test returns PASS only as target nvgpu_writel_check() always returns
* void.
