video: tegra: host: add NVHOST_IOCTL_CHANNEL_GET_CLK_RATE_LEGACY

With module branching updating user space and kernel space IOCTL
definition at the same time is impossible.

This patch adds temp IOCTL NVHOST_IOCTL_CHANNEL_CLK_RATE_LEGACY.
This temp IOCTL getting added to update NVHOST_IOCTL_CHANNEL_GET_CLK_RATE
_IO macro parameter.
