Move `PSR_Off` out of `Power_And_Clocks_Haswell`

Allowing other platforms to use the Haswell-specific power and clocks
package precludes with'ing other Haswell-specific units unless they are
placed under `haswell_shared` as well. This unnecessarily forces several
implementation-specific details to be public, breaking encapsulation.

The only benefit is that the `PSR_Off` procedure gets to be shared.
However, we can allow reusing said procedure without having to destroy
encapsulation, by moving it elsewhere. As the SRD/PSR registers are tied
to transcoders, place `PSR_Off` and the corresponding definitions to the
common `Transcoder` package. Also update the callers of this procedure
to refer to the `Transcoder` package, and then drop the visibility of
the power and clocks package for Haswell.
