Like all the other drivers, let's initialize the structure a compile time
instead of init time.

The states #1 and #2 are not enabled by default. The init function will
check the features of the board in order to enable the state.

A careless look at the code shows that the last entry in the
pinmux_gpios seems to be GPIO_FN_IRQOUT. However, entries are ordered by
the GPIO number, as the PINMUX_GPIO macro is expended to an indexed
array initializer. The last entry in the array is thus GPIO_FN_STATUS0.
