gpio: siox: normalize return value of gpio_get()

gpio_siox_get() returns the masked bit from the cached input or output
byte, so for most lines a high level reads back as a value between 2
and 128 instead of 1. The GPIO get callback is expected to return 0 or
1 (or a negative error code).

Since commit 86ef402d805d ("gpiolib: sanitize the return value of
gpio_chip::get()"), gpiolib rejected such values with -EBADE and reads
of a high line failed. Commit ec2cceadfae7 ("gpiolib: normalize the
return value of gc->get() on behalf of buggy drivers") made gpiolib
clamp the value instead, but it now warns on every such read.

Normalize the value returned by gpio_siox_get() to the [0, 1] range.
