Subject: [PATCH v2 09/34] ARM: tegra: apalis_t30: annotate uarts and move compatible to board

From: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Annotate UARTs and move the serial UART "nvidia,tegra30-hsuart"
compatible definitions from the carrier board to the module level device
trees. One could still override this in a custom carrier board device
tree if required.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@...adex.com>

Changes in v2:
- Also move serial UART "nvidia,tegra30-hsuart" compatible to module
  level device trees.
