As a uart1 node is added into sun8i-reference-design-tablet.dtsi, simply 
use it in iNet D978 rev2 device tree.

I'd like to see more consolidation before that change is needed. If we 
find more boards using that, it will make sense, but for a single 
board it's not worth it. 

At least 2~3 Q8 A33 tablets in #linux-sunxi are found to have
rtl8703as, which contains UART bluetooth. (including mine)

Still, I'm not fond of creating a default on such a low count sample
of (out-of-tree) DTs. Support and enable the bluetooth on more boards,
and then consolidate.

In fact, what I want to do is to get the node ready-to-be-okay in Q8
dts, so it can be enabled by either u-boot command or (theortically)
Hans de Goede's q8-hardwaremgr, just like what is done at
touchscreen node.

If your plan is to enable all the combinations possible accross the Q8
tablets and let the bootloader/user figure it all out, then it's not
going to happen, sorry.
