Actually the GPIOLIB dependency is related to BT_RTL usage, if I
understand the code right. There's much more to be fixed though:
currently all "btrtl" code in hci_h5.c is unconditionally compiled in,
which it shouldn't be (it should depend on BT_RTL). There should
probably be a similar Kconfig option to select BT_RTL for
BT_HCIUART_3WIRE like there is for btusb with BT_HCIBTUSB_RTL.

Would you, or perhaps Jeremy (who introduced this code) be willing to
submit a patch for it? We need to get this fixed for the last 4.19
bluetooth-next pull request, which is due this week.
