[Intel-gfx] [PATCH] drm/dp: Make space for null terminator in the DP device ID char array

[Dhinakaran Pandiyan]

The DP device identification string read from the DPCD registers is 6
characters long at max. and we store it in a char array of the same length
without space for the NULL terminator. Fix this by increasing the array
size to 7 and initialize it to an empty string.
