gsmcomp.c: bumping trace partition size to 220 like in gprscomp.c This change is safe in terms of RAM usage because all of these partition pools have already been moved from XRAM to IRAM earlier, and our IRAM usage in VO configs is currently quite low - the one near the limit is XRAM on C11x.

   MODULE  : MFW_CAM

   PURPOSE : This module contains Camera Interface functions.

   HISTORY:

       Nov 29, 2005 REF: MMI-SPR-33833(OMAPS00055207)- x0035544
       MMI making Riviera calls without using proper header files. So added appropriate header files.
       
    	Sept 15, 2005 REF: LOCOSTO-ENH-34257 - xpradipg
	Description: Locosto: MIgration to New LCD APIs
	Solution: Migrated to New APIs by replacing the old driver APIs with
	corresponding New LCD APIs

   	Sep 13, 2005    REF: SPR 33992 xdeepadh	
	Description: Image viewer cannot open file when saved in high quality	
	Solution: The quality factor has been rearranged to support saving	the images within 64KBlimit.

 	Aug 22 2005, xpradipg - LOCOSTO-ENH-31154
 	Description:	Application to test camera
 	Solution:	Implemented the camera application with following functionalities
 			preview, snapshot and image saving.
