tegra: stingray: initialize suspend platform data

configure the suspend platform data for stingray with conservative
values for the PMU timers, and specify LP1 (DRAM in self-refresh,
core voltage on) as the default suspend mode.

to configure LP2 (DRAM active, core voltage on) as the suspend mode,
set .dram_suspend = false in stingray_suspend.
