Add vga_switcheroo option

You might know that there are laptops with more than one video adapter. People use vga_switcheroo to disable one of those adapters to conserve battery power. 

It's a good idea to switch adapters as early as possible. Initramfs seems to be a good place to do this.

With attached patch it is possible to use, for example, "vga_switcheroo=IGD,OFF" to switch to integrated videocard and disable another one.

Sorry, I forgot about documentation.
I don't know, maybe it's better to squash theese three patches into a single commit...
