hardware/msm7k: Fix aspect ratio in HDMI UI

Browse Source 
For portrait mode: Actionsafe width depends on actionsafe
height, thus maintaining the  aspect ratio.
User entered value for actionsafe width doesn't matter.

For landscape mode: Both, user entered actionsafe width
and height matter. Aspect ratio may change, in an attempt to fill
up the TV screen till the edges to avoid overscan/underscan.

Picks actionsafe rectangle as the final rectangle.
