Smart gpios fixes - now without cleanup of smart_gpio.cpp (#758)

* smart_gpio.cpp: check _add return values

And occupy gpiochip's pin range if disabled of failed. So base will
align with enum.

* TLE8888: cleanup, move high level code to smart_gpio.cpp

* smart_gpio.cpp: fix compilation when BOARD_EXT_GPIOCHIPS == 0

* board-subaru: fix compilation after latest smart_gpio updates

* tle8888: now we have all 28 pins supported
