pwm: tegra: Use DIV_ROUND_CLOSEST_ULL() instead of local implementation
Use macro DIV_ROUND_CLOSEST_ULL() for 64-bit division to closest one instead of implementing the same locally. This increase readability. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
