This fixes problems with having different DDK versions in userland and kernel:

[   76.865447] PVR: Installing MISR with cookie c09e9250
[   76.889556] PVR: Installing device LISR SGX ISR on IRQ 53 with cookie c793bf00
[   76.889709] PVR: OSUnMapPhysToLin: unmapping 65535 bytes from c89e0000
[   76.889831] PVR: SysFinalise: Version string: SGX revision = 1.2.0
[   76.890136] PVR_K: (FAIL) SGXInit: Incompatible driver DDK revision (905891)/device DDK
revision (2198402).
[   76.890289] PVR_K:(Error): PVRSRVFinaliseSystem: Failed PVRSRVDevInitCompatCheck call
(device index: 0) [449, drivers/gpu/pvr/pvrsrv.c]
[   76.890533] PVR_K:(Error): BridgedDispatchKM: Initialisation failed.  Driver unusable.
[4783, drivers/gpu/pvr/bridged_pvr_bridge.c]

Now userland and kernel are both synced to DDK revision 2198402 (Android 4.2.2).
