ARM: tegra: power: Added global EDP Capping table
- Added table with EDP Capping values for different SKUs/regulator
currents in new file edp.c
- New entry point tegra_init_cpu_edp_limits()
- Added DebugFS entry under debug/edp to list the currently
selected EDP table
- Populated EDP table in edp.c with data from Bug 844268
- edp.c keeps main EDP table; cpu-tegra.c and board-cardhu-power.c
both read from there
Bug 840255
