Updated the tests on tc

Found out why TC1 and TC2 would not work. Activated wrong peripherals in PMC. Now the tests run tests on TC0, TC1 and TC2, all on channel 0. All is working.
All tests working on TC

The tests are running at TC0 - channel 0, TC1 - channel 1 and TC2 - channel 0. This is to test that all three base adresses and all the offsets are working even if it is a different channel.

Also the delays are working. One fast delay, one a bit slower and one really slow.
Merge branch 'mcu__timers_temp' into mcu_timers
