DCP firmware 14.7 returns raw EDID bytes without the eight-byte prefix used by older firmware. It also uses the generic 48-byte variable-data message header with 32-bit maximum size, return code, and used size fields. Describe that message layout accurately, check its return code and bounds, and retain the legacy prefix for older firmware. Signed-off-by: a-ramses <abdicheramzi@gmail.com>

Add T6030 DisplayPort PHY support and device-tree wiring, with DCP and RTKit fixes. USB-C display output and EDID retrieval are tested. HDMI output works with a forced mode; HDMI EDID parsing remains unresolved.
