[arm/tegra] hsuart: Configuring tristate correctly.
To enable the tristate of the pin, the argument should be either
TEGRA_TRI_TRISTATE or true and for setting it to normal, the
argument should be either false or the TEGRA_TRI_NORMAL.
The code was passing the value of the argument in reverse, for tristate
it was passing the false and for normal it was true.
Passing the correct argument value for setting the tristate and normal.
