gpu: nvgpu: volt: Remove unsused code in volt_policy

Browse Source 
Removed unused split rail structs and functions which
are no longer valid for turing. Split rail structs are
retained in supersurface boradobj interface structs
as this is needed by PMU. Can be removed once the PMU
code is updated.
