UART1 is connected to the bluetooth part of RTL8723BS WiFi/BT combo card
on iNet D978 Rev2 board.
Enable the UART1 to make it possible to use the modified hciattach by
Realtek to drive the BT part of RTL8723BS.
On the board no r_uart pins are found now (the onboard RX/TX pins are
wired to PF2/PF4, which is muxed with mmc0), so also disabled it.

Oh I forgot to add a patch version number...
It's PATCH v3.
(But it seems that I should send a v4 to split the dtsi change and dts change.)
