mdss: mhl3: Add driver for MHL Transmitter 

Code drop from https://github.com/siliconimageinc/sii8620


taken from commit 20b4c581d705cffce422bc79c2bacf7ed5363beb

"Posting driver 1.03 release candidate.

Version 1.03.19

Signed-off-by: default avatarMikhail Amchislavsky <Mikhail.Amchislavsky@siliconimage.com&gt;">

Adding driver for SiI 8620 MHL transmitter.
Integrated the files into drivers/video/msm/mdss/mhl3/.

Removed unnecessary files:
apq8074_kernel_update/apq8074-dragonboard.dtsi
apq8074_kernel_update/board-8974-gpiomux.c
apq8074_kernel_update/msm8974.dtsi
apq8074_kernel_update/sii6031/msm_otg.c
apq_build.sh
build
build_num.txt
clean

Moved files relating to SiI 6031:
apq8074_kernel_update/sii6031/msm_otg.c
apq8074_kernel_update/sii6031/si_6031_switch.h
apq8074_kernel_update/sii6031/sii_6031/Kconfig
apq8074_kernel_update/sii6031/sii_6031/Makefile
apq8074_kernel_update/sii6031/sii_6031/si_6031_switch.c
into drivers/video/msm/mdss/mhl3/sii6031/.

	  This option controls whether or not Silicon Image MHL transmitter

	  drivers include support for Media Data Tunneling (MDT).  MDT

	  support enables HID events generated by HID devices attached to

	  an MDT capable MHL sink to be passed over the MHL connection

	  to the system.
