drm/i915: Use the AUX_IO power domain only for eDP/PSR port
Use the AUX_IO_A display power domain only for eDP on port A where PSR is also supported. This is the case where DC states need to be enabled while the output is enabled - ensured by AUX_IO_A domain not enabling the DC_OFF power well. Otherwise port A can be treated the same way as other ports with an external DP output: using the AUX_<port> domain which disables the unrequired DC states. This change prepares for the next patch enabling DC states on all ports supporting eDP/PSR besides port A. v2: - Check the encoder PSR capability instead of PSR being enabled in the crtc_state, as the latter can be changed with a fastset.
