uapi: hbtp_input: exposes first and last ABS_MT parameter



When user space sets multi-touch parameters on hbtp_input driver
through ioctl, it needs to know the total number of ABS_MT parameters
that are supported by kernel. Add two macros for the first and the
last ABS_MT parameter to expose to user space.
