ble_app_all_in_one app not updated for SDK 6.0.2

I'm bringing up an app on the DA14585. Just to make sure I had everything I needed, I started with the ble_app_all_in_one app.

I've run into a couple of issues:
uart2_init() now takes 3 parameters, but this example and a couple of others still only provide 2. Fixed that in my copy.

Also, the defines for the UART changed from
GPIO_UART2_TX_PORT
and
GPIO_UART2_RX_PORT

to
UART2_TX_GPIO_PORT
and
UART2_RX_GPIO_PORT

and similarly for the pin macros.
