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_KBD

   PURPOSE : keyboard handling functions

   EXPORT  :

   TO DO   : adjust PEI/driver interface

   HISTORY :

   Sep 14, 2007	REF: OMAPS00145862  Adrian Salido
	Description:	FT - MMI: Wrong trace class 
	Solution:		changed some event traces to function traces because the information content of 
				this is low for non-MMI people and against TI coding convention.
				
   Oct 13, 2006 REF: OMAPS00097121 - x0039928
   Description: Keyboard pressed in a loop. KBP_R after suspend-resume
   Solution : If the Auto press timer expires mmi checks the bsp kpd status and accordingly
   sets auto key in the key map.
   
   Sep 18, 2006 REF: OMAPS00094426 - x0039928
   Description: Locosto - KPD Release event would NOT be generated if a key is pressed 
   several times in a short period of time
   Solution : If the long press timer expires mmi checks the bsp kpd status and accordingly
   sets long press bit in the key map.

    xrashmic 22 Aug, 2004 MMI-SPR-32798
    Adding the support for screen capture using a dynamically assigned key.

   Apr 03, 2005 REF: CRR 29988 - xpradipg
   Description: Optimisation 2: Reduce the keyboard buffer and the dtmf buffer
   size
   Solution : The keyboard buffer is reduced to 20 from 50
