This should probably be enabled using an dt-overlay, there is no UART
device embedded on the board and the reason I left it disabled in
original board DT submission.
On second thought maybe they should be enabled, think PCIe and USB lines
on the M.2 Key E is already enabled by default. I probably only tested
with a pcie/usb wifi/bt card and not a sido/uart wifi/bt card.
