Create variables

1.
Create a module software instance structure for the TC module to store the TC driver state while it is in use.
```
struct tc_module tc_instance;
```
Note: This should never go out of scope as long as the module is in use. In most cases, this should be global.
2.
Create a module software instance structure for DMA resource to store the DMA resource state while it is in use.
```
struct dma_resource example_resource;
```
Note: This should never go out of scope as long as the module is in use. In most cases, this should be global.
