No need to reset MIPI CAL
Could you please explain why. There is a calibration

tegra_i2c_runtime_resume does not disable prior enabled clocks
properly.
This patch fixes it.

VI I2C is on host1x bus and is part of VE power domain.
During suspend/resume VE power domain goes through power off/on.
So, controller reset followed by i2c re-initialization is required
after the domain power up.
This patch fixes it.

Tegra internal TPG mode is only for Tegra vi and csi testing
without a real sensor and driver should default support real
sensor.
So, This patch adds CONFIG_VIDEO_TEGRA_TPG and enables Tegra
internal TPG mode only when this config is selected.

VI I2C is on host1x bus so APB DMA can't be used for Tegra210 VI
I2C and there are no tx and rx dma channels for VI I2C.
So, avoid attempt of requesting DMA channels.
