Snapdragon 835 Laptop Results:

4.15 boots to the first 4 lines before kernel
4.18 boots most of the kernel, stops for a bit, then suffers with an rshed crash
5.0 boots to the end of the kernel log, then the screen goes blank

Without this patch on the 835 laptops the user sees grub and then
nothing and is left sad; however, with this patch the user sees some
form of kernel life on the laptops and is left hopeful - which leads
them to start looking around for fixes and help with the solution.

Additional patches will need to be backported but without this patch
it's a non-starter until 5.1 or after.

If there is little to no regression risk as this adds a kernel parameter
and this is required to enable these platforms to boot, if not other
platforms, I would argue to include the patch for at least Disco if not
Bionic since random people will attempt to boot the LTS release. Thank
you for building the test kernel.
