mb/google/brya : Set EPP value for Vell board

The patch sets the EPP to 50% (0x80) for Vell. With EPP at 50%, the Vell
system demonstrated better power improvement without sacrificing the
performance.

PLT Results(Perf) with EPP@40% and EPP@50%:
	EPP@40%: Device1-656 mins, Device2-664 mins.
	EPP@50%: Device1-678 mins, Device2-677 mins.

In short, with EPP@50%, PLT KPI ran for more than 13 to 22mins compared
to EPP@40%.
