Tegra: enable SDEI handling

Browse source 
This patch enables SDEI support for all Tegra platforms, with
the following configuration settings.

* SGI 8 as the source IRQ
* Special Private Event 0
* Three private, dynamic events
* Three shared, dynamic events
* Twelve general purpose explicit events

Verified using TFTF SDEI test suite.
