The reset GPIO was marked active-high, which is against what's specified
in the documentation. Mark the reset GPIO as active-low. With this
change, Bluetooth can now be used on the i9100.

Also switch away from using the deprecated 'host-wakeup-gpios' property,
and use a 'host-wakeup' interrupt instead.

Thanks for the patch, but please split it into two commits and add a
"Fixes" tag for the "reset-gpios" one.

All rest looks good, nice patch!

Best regards,
Krzysztof
