HSI: cmt_speech: Add cmt-speech driver
Introduces the cmt-speech driver, which implements
a character device interface for transferring speech
data frames over HSI/SSI.
The driver is used to exchange voice/speech data between
the Nokia N900/N950/N9's modem and its cpu.

Since the original driver has been written for 2.6.28 some
build fixes and general cleanups have been added by me:
* fix build for 4.0 kernel
* replace GFP_ATOMIC with GFP_KERNEL in cs_alloc_cmds()
* add sanity check for CS_SET_WAKELINE ioctl
* cleanup driver initialisation
* rename driver to cmt-speech to be consistent with
ssi-protocol driver
* move cs-protocol.h to include/uapi/linux/hsi, since
it describes a userspace API
* replace hardcoded channels numbers with values provided
via the HSI framework (e.g. coming from DT)
