Correct gpio driver (#9)

* Correct gpio driver

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

* Simplify blinky example

Make it look like every other HAL for consistency. While at that, also
rename the example to match the name used by other HALs.

* Add some documentation to GPIO driver

* Enable GPIO clocks during HAL initialization

Provide the user with working GPIO clocks.
