Add a suitable sleep configuration for uart3 to support Bluetooth

If QUP function is selected in sleep state, UART RTS/RFR is pulled
high
during suspend and BT SoC not able to send wakeup bytes. So, configure
GPIO mode in sleep state to keep it low during suspend.

check your config? I tried:

...and also checked patchwork servers. I only see patch 1 and 2. I
think Bjorn usually applies from patchwork so this'll likely be a
problem...

I believe things in this section are supposed to be sorted
alphabetically. Thus "qup..." should be sorted before "trackpad..."
Ok.
