surfaceflinger: odd hw rotation (90/270) patch for swapping width/height

Browse Source 
This patch works in addition to the following commit
re-implementing ro.sf.hwrotation:
7d283431ef

When using values of 90 and 270 for ro.sf.hwrotation the
LCD width and height also need to be swapped to display properly.

Change-Id: I2874fdb8f8d8b855df6d62d338c9a22360491973
NOTE: This patch does not fix the initial startup of bootanimation
