[PATCH] video: fix no display when serial console is disabled

[Desapogu Jayaramudu]

When the serial console is disabled in coreboot configuration,
no display output is observed during boot.

This happens because DBG2 (Debug Port 2 table) configuration
is required for proper UART initialization and affects the
video initialization path.

Fix this by ensuring DBG2 is correctly configured as a
16550-compatible UART, allowing video initialization to
proceed independently of serial console settings.
