[7.1.r1][DNM] Add missing commits from LA.UM.7.1.r1-16600-sm8150.0

[stefanhh0]

A cherry-pick PR to have all commits included that are in:
https://source.codeaurora.org/quic/la/kernel/msm-4.14/tag/?h=LA.UM.7.1.r1-16600-sm8150.0

Please review and test. This PR is already running on Yoshino/Lillac without any problems.

See especially: bf5da44. This is an idea how to identify what we have merged back via cherry-picking. Please provide feedback.

I have also included the camera commits, since all of them are just about adding the atoll cam, thus I believe it can be merged back together with the other changes and should not affect the other cameras we are already using.

Additionally I have created the special commit 1fcd973 the removes a remnant. I think that is a pretty harmless cleanup.

This PR supersedes: #2327 and #2156 in consequence those should just be closed and not merged back.

Aaaahhhhh! Empty commit! Ahhhhh my eyes! :D
Please remove that empty thingy! :p

Also, one specific test is necessary here:

1. Grab a random (working) microsd, insert it in the tray, boot your phone, let it go to sleep;
2. Wake it up, then remove the tray: any spectacular failure happening? If working, then place it back in and...
3. Reboot, sleep again, don't wake it up, remove the tray: does it wake up? Still fine?
   Note: when putting the tray back in, the microsd card shall be recognized again!

Please execute this test on both old (Yoshino) and new (Tama or Kumano) platforms before merging this.
Of course the reason why I'm asking the double test is that new and old platforms are managing the tray insertion in a slightly different way.
P.S.: Nile/Ganges can be safely ignored if both tests succeed!

Tested it on yoshino/lilac:

1. Insert microsd, booted, wait for sleep, wake up, remove tray with microsd and re-insert works as expected. The microsd is available after being re-inserted.
2. Reboot, wait for sleep, don't wake up, remove tray ans re-insert works as expected. The microsd is available after being re-inserted. Removing the tray does not activate the display, if a wake-up is triggered as you expect it I can't say for sure. Maybe you can see that in the attached log.

Should be this from the kernel.log:

A sidenote, when removing the tray. A message pops up: "SIM card has been removed", and when re-inserting the tray a message "SIM card has been added" is shown. Those messages have been coming as well before this PR. However the removal of the tray does not remove the SIM card. but only the microsd.

From my point of view the test was successful on yoshino/lilac.

The commits regarding camera probably don't affect any Sony device or do they?

@kholk @stefanhh0 What kind of changes are left in this tree that can improve sm8150 support?
