Multi-touch Protocol is divided into two types:
Type A --> for devices handling anonymous contacts, the protocol
describes how to send the raw data for all contacts to
the receiver.
Tyep B --> for devices capable of tracking identifiable contacts,
the protocol describes how to send updates for individual
contacts via event slots.
Before this patch, our driver use type A, but wayland 1.6(GPU team)
just call type B contact to check the multi slots number. Besides,
type B can also be used in Android and Yocto, so this patch use
type B to replace type A.
The upstream EETI egalax touch driver use type B multi-touch protocol,
so this patch just use the upstream driver to replace the current
egalax touch driver.
