The KUnit wrapper script interfaces with the two modules

interface for running KUnit tests. This interface allows the caller to

Adds the concept of spying like in Mockito
(http://static.javadoc.io/org.mockito/mockito-core/2.20.0/org/mockito/Mockito.html#spy-T-).
This allows a function declaration to be labled as spyable which allows
the function to be mocked *and* to allow the mock to invoke the original
function
This mocks out some iomem functions (functions like readl and writel),
for mocking hardware interfaces.
