OSTimer updates (#24)

* Initialize OSTIMER0 during HAL initialization

Provide the user with a working time driver.

Signed-off-by: Felipe Balbi <[email protected]>

* Handle time_driver interrupt internally

* Gate `time-driver` impl behind a `time` flag

Also prevents creation of an `Ostimer` instance if the `time`
feature is active.

* Remove some dead code
