Display DDI ports are enumerated as PORT_A,PORT_B... . The enums are
also used as an index to access the DDI_BUF_CTL register for the port.
With the introduction of TypeC ports, new enums PORT_TC1,PORT_TC2.. were
added starting from enum value 4 to match the index position of the
DDI_BUF_CTL register of those ports. Because those early platforms had
only 3 non-TypeC ports PORT_A,PORT_B, PORT_C followed by TypeC ports.
So the enums PORT_D,PORT_E.. and PORT_TC1,PORT_TC2.. used the same enum
values.
Driver also used the condition `if (port > PORT_TC1)` to identify if a
port is a TypeC port or non-TypeC.
>From XELPD, additional non-TypeC ports were added in the platform
calling them as PORT D, PORT E and the DDI registers for those ports
were positioned after TypeC ports. So the enums PORT_D and PORT_E can't
be used as their values do not match with register position. It led to
creating new enums PORT_D_XELPD, PORT_E_XELPD for ports D and E.
The condition `if (port > PORT_TC1)` was no more valid for XELPD to
identify a TypeC port. Also it led to many additional special checks for
ports PORT_D_XELPD/PORT_E_XELPD.
With new platforms indicating that the DDI register positions of ports
can vary across platforms it makes no more feasible to maintain the port
enum values to match the DDI register position.
Port DDI register position is now maintained in a separate datastructure
part of the platform device info and ports are enumerated independently.
With enums for TypeC ports defined at the bottom, driver can easily
identify the TypeC ports.
Removed a WARN_ON as it is no longer valid. The WARN was added in
commit - "327f8d8c336d drm/i915: simplify setting of ddi_io_power_domain"
The ddi_io_power_domain calculation has changed completely since the
commit and doesn't need this WARN_ON anymore.
