Subject: [PATCH 0/6] Add camera access keys, IdeaPad driver improvements

Nowadays many laptops have camera access keys, yet there is no usage codes
mapped to them, even though it's introduced in HUTRR72. Start point of
this patch series was adding it and making IdeaPads send it to userspace.
But later I discovered that camera_power attribute of ideapad-laptop
driver on my IdeaPad 520-15IKB doesn't work, so I can't toggle it with
that. I managed to find a way to check whether an IdeaPad supports
camera_power attribute (which sends VPCCMD_W_CAMERA to EC), don't expose
it to sysfs so userspace will know that it can't toggle camera access via
camera_power, in my case, after receiving KEY_CAMERA_ACCESS_TOGGLE.

Along the way I discovered that old IdeaPads, like S10-3, may not be able
to toggle their touchpad as a regression of a commit aimed for newer
IdeaPads, so I reverted it.

Also I noticed that I can get/set the state of my keyboard light,
so one of the patches also adds supports for this kind of keyboard lights,
which I call "partially supported keyboard lights". I expect that commit
to add keyboard light support for 520-15IKB, 330-17ICH, 5 (15) and more.
Currently only tested on 520-15IKB.
