* [PATCH] drm: include linux/seq_file.h as needed

The addition of the debugfs info created references to seq_puts() and
seq_printf(), but relied on the debugfs header to be included implicitly,
which apparently doesn't happen all the time, as seen from this randconfig
build output:

drivers/gpu/drm/drm_dp_helper.c: In function 'drm_dp_downstream_debug':
drivers/gpu/drm/drm_dp_helper.c:552:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
drivers/gpu/drm/drm_dp_helper.c:560:3: error: implicit declaration of function 'seq_puts' [-Werror=implicit-function-declaration]

Adding the extra include brings back a clean build.

Fixes: 80209e5f2c42 ("drm: Add DP branch device info on debugfs")
