linux-ezx 2.6.21: update to r2011:

r2011: call send_readurb on bp_rdy signal from BP to keep BP communication active
       add asoc pxa2xx-ssp.c driver from asoc-v0.13rc3
r2010: * pxa-kbd.patch: Fix pxakbd bug: direct keys were not passed to userspace
       * a780-kbd.patch: Cleanup keycodes definition for a780, use unique keycodes so
        to avoid the double event problem occurring when the same keycode is used more
        than once. 
r2003: core:	EZX subsystem
       ezx-phone.c file for each phone
                BP handshake code on a platform_driver (and another .patch)
       pm:      fully functional suspend/resume (except for BP)
                reboot/poweroff
       new:	a780 flip
                e680 lock switch
       bp:	Kconfig entry to disable BP handshake (the watchdog dont start if we dont try to handshake)
       other:	delete obsolete files
r2002: * Implement vibrator handling for a780 using the leds class.
r1999: * Port and readapt ezx-backlight patch. Let's use again the backlight class
         to handle lcd brightness.
r1998: * Port leds patches for A780 and E680 (we still pollute ezx.c for now)
