19213d7a65 sysinfo: gpio: fix loop over DT "revisions" array
There can certainly be a lot more elements in the "revisions" (and
"names") arrays than there are gpios used to form the trinary number
we're searching for; we simply don't know the array size up-front.

Nor do we need to, because the loop body already knows to recognize
-EOVERFLOW as "not that many elements present" (and we have a test
that specifically ensures that dev_read_u32_index() returns exactly
that). So just drop the i < priv->gpio_num condition.

While in here, fix the weird placement of the default: keyword.

54aa07fdfc sysinfo: Add gpio-sysinfo driver
This uses the newly-added dm_gpio_get_values_as_int_base3 function to
implement a sysinfo device. The revision map is stored in the device tree.
