Subject: [PATCH] Bluetooth: hci_nokia: select BT_HCIUART_H4
Git-commit: c42c88e6c84d081397965a024fa09ab9b11e7938
Patch-mainline: v4.13-rc1
References: bsc#1051510

We see the following build failure with CONFIG_BT_HCIUART_NOKIA=y and
Config_bt_hciuart_h4=n: 

Drivers/bluetooth/hci_nokia.c: In function 'nokia_recv':
drivers/bluetooth/hci_nokia.c:644:18: error: implicit declaration of function 'h4_recv_buf' [-Werror=implicit-function-declaration]
...

Fix this by selecting the BT_HCIUART_H4 symbol like all the other users
of the protocoll.
