fix : Converge the Ring-LL region at TUNER_MAX_RANKS

Currently the Ring-LL region for AG0x0 and RS0x0 starts with
the point {0, 16} and extends till {TUNER_MAX_SIZE, TUNER_MAX_RANKS}.
But the polygon was not completely closed without a point on the y-axis.
Added a points {0, TUNER_MAX_RANKS}. This ensures the polygon is closed
correctly.
