drm/i915: Sanitize the port -> DDI/AUX power domain mapping for each platform
Atm the port -> DDI and AUX power domain mapping is specified by relying
on the aliasing of the platform specific intel_display_power_domain enum
values. For instance D12+ platforms refer to the 'D' port and power
domain instances, which doesn't match the bspec terminology, on these
platforms the corresponding port is TC1. To make it clear what
port/domain the code refers to add a mapping between them which matches
the bspec terms on different display versions.
This also allows for removing the aliasing in enum values in a follow-up
patch.
v2: Add the functions to intel_display_power.c, use
intel_display_power_ prefix.
