media: tegra: replace nvhost_device to platform_device

According to nvhost API changes, this patch convert nvhost_device
interface to platform device interface.

Since nvhost_device_data is in the platform_data for
tegra_vi01_device, our specific tegra_platform_data has to be passed
as a private_data of nvhost_device_data from a board file.
