video: tegra: host: Rework T132 power features

T132 power features were disabled using a single loop that went
through host1x devices and removed callbacks. Even though the solution
is simple and the loop will in the end be removed, it does not allow
enough control before all power features have been verified.

This patch creates new platform data structures for T132. The code
goes through T132 devices and if an override for platform data is
available, the original pdata is replaced by the override version.
