Expose method for registering and unregistering HSI clients, so that
client drivers can register other client drivers.

This is useful for HSI drivers, which want to use the functionality
of other HSI drivers. For example the N900 modem driver can load HSI
drivers for mcsaab protocol and speech protocol.

Don't document "private:" fields with kernel-doc notation.
If you want to leave them fully documented, that's OK, but
then don't mark them as "private:".

Remove custom hack and make use of the notifier chain interfaces for
delivering events from the ports to their associated clients.
Clients that want to receive port events need to register their callbacks
using hsi_register_port_event(). The callbacks can be called in interrupt
context. Use hsi_unregestier_port_event() to undo the registration.

Adds HSI framework in to the linux kernel.

High Speed Synchronous Serial Interface (HSI) is a
serial interface mainly used for connecting application
engines (APE) with cellular modem engines (CMT) in cellular
handsets.

HSI provides multiplexing for up to 16 logical channels,
low-latency and full duplex communication.
