Tegra194: introduce tests to verify the Video Memory resize interface

Tegra platforms provide support to program the Video memory aperture and
increase or decrease the size at run time.

This test verifies the interface for the following positive and negative
scenarios:

* verify that incorrect input parameters are handled properly
* verify that the memory region is programmed and can be resized later
* verify that no information is leaked after the resize operation
