Bug description:
[Impact]
The Ubuntu kernel is not currently bootable on various arm64 laptops (HP Envy
x2, Asus NovaGo, Lenovo Miix 630, Lenovo Yoga C630, Samsung ...) because of EFI
memory permissions/restrictions. The reason is explained in the commit supplied
below.
[Test Case]
Install and boot Ubuntu on one of the above arm64 laptops.
[Fix]

[Regression Risk]
This commit adds support for an optional kernel command line parameter so
there is minimal to no risk.
