42eed42bac sh: improve pinmux support for single direction pins 
This patch improves the support for gpio pins that are hard wired
to either input or output and lack control register association.
A special force enum id is used to allow use without control
register but still mark the gpio pin as input or output.

ed0b2ef55a sh: Update gpio_set_value() pin value handling 
This patch updates the pinmux code to use the boolean value for
the function gpio_set_value(). Without this patch values other
than 0 and 1 will result in incorrect GPIO settings.

2967dab1ae sh: GPIO and pinmux base code 
This patch adds gpio code together with the pinmux table parser.
In the future we should optimize this and switch back to gpiolib.
