[PATCH 1/5] ARM: tegra: rework fdt_serial_tag_setup_one

[twarren at nvidia.com]

From: Stephen Warren <swarren at nvidia.com>

Reword fdt_serial_tag_setup_one() so that the types it uses aren't tied
to CONFIG_SERIAL_TAG, and rename the function to better indicate its
purpose. This will allow it to be re-used by future board info related
code.
